Hi all,
since I've said goodbye to my Milestone, in these days, prior to selling it, my good behavior said to me "okay, no customkernel, you can't help with RSA...so Milestone owners are ****ed...ouh, no, wait!"
...and then prior to selling it I've tested some things and I've found that sysctl is working!
Since sysctl is working and I'm on Linux from about 10 years, I've been played with our kernel in Milestone and tested some parameters.. and I've had a speedup in my daily operations: browse the net with Dolphin Browser HD, play some games, sync email, make calls, sms etc... and I've found that my Milestone is way more responsive and feels smoother!
Sysctls tested on the great CyanogenMod port by nadlabak.
So, well, here's the script. Feel free to execute it at boot (if you execute it at boot, your phone will boot slightly faster) and/or to integrate in your custom nandroid ROMs
Code:
#!/system/bin/sh
sysctl -p
#
#Disable normalized sleeper
#
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
#
# Memory management
#
echo 2048 > /proc/sys/kernel/msgmni
echo 64000 > /proc/sys/kernel/msgmax
echo 268435456 > /proc/sys/kernel/shmmax
echo "500 512000 64 2048" > /proc/sys/kernel/sem
sysctl -w net.core.wmem_max=524288
sysctl -w net.core.rmem_max=524288
sysctl -w net.ipv4.tcp_tw_recycle=1
sysctl -w net.ipv4.tcp_rmem='6144 87380 524288'
sysctl -w net.ipv4.tcp_wmem='6144 87380 524288'
sysctl -w kernel.sched_latency_ns=600000
sysctl -w kernel.sched_min_granularity_ns=400000
sysctl -w kernel.sched_wakeup_granularity_ns=400000
EDIT: UPDATE N.3
This script makes the Linux kernel to take a little more RAM, so I don't recommend to use it in HTC Sense builds, since Sense is already crashing because of heavy RAM usage, but with CM and LauncherPro, with a lot of progs open in background I've never went out of RAM!
NOTE: Make sure that you've got echo and sysctl in /system/xbin/ otherwise this won't have any effect!
Even if I'm returning to HTC I'm sad for my old Milestone, I like its shell so much...it's a really beautiful device!
Hoping for the best for u, Milestone users

Very interesting. Could you please advice what I need to do to execute the script at boot?

ciao kholk
Want to know if you put a sysctl binary in xbin?
Cause your script suppose to have sysctl in xbin right?
Can you make a download of it? Or is a symlink from busybox?
Grazie per questa drittona per il pietrone
EDIT: okok resolved, had to --install busybox -s xD
NO PROBLEM now testing!!
This script is supposing that you've got echo and sysctl in /system/xbin/
If you haven't got echo and sysctl in /system/xbin/ this script won't have any effect.
And how would i go about obtaining those?
Sent from my Milestone using XDA App
Install busybox and with it you should have installed those.
I didn't think sysctl would work on this kernel. Since it does, here's some more optimizations that I know work for Eclair and earlier:
Code:
/system/xbin/sysctl -w kernel.sched_latency_ns=600000
/system/xbin/sysctl -w kernel.sched_min_granularity_ns=400000
/system/xbin/sysctl -w kernel.sched_features=24188
The default latencies were a little ridiculous. And the CFS features disabled here are pointless, even on desktops.
That said, thanks for pointing out that it works! Much appreciated. Best of luck with your HTC device.
Very nice, thanks kholk!
Thanks xslntx!
Script updated.
-- Absolute path not needed.
-- Added scheduler tuning for granularity latencies
-- Normalized sleeper disabled.
Testing it with great results (in combination with xlsntx parameters)
graphic performance are improved, usage is clearly improved,
in opposition to that bench are lower, I mean, I donot understan:
In Quadrant, I have nearly 3\4 fps MORE than normal in EACH test (except for the planet one) -wich is nealrly the performance a droid2 has...- and have a result like 20\25 point lower...dunno...another dimostration that benchs aren't much reliable...
Sounds great!
So, I have Busybox installed. How do I actually activate the script file?
Just placing a file, for example "optimize" in system/xbin with the script content and thats it? Or do I have to do anything else to actually load the optimization from boot?
@89luca89
Can you add this modification in next update to your OpenRecovery with andrea???
As you have more knowledge, plsease make your test and put the best combination in next update to your OpenRecovery...
Just a question - can I use these commands also with the stock(rooted) ROM? I don't have CM6 and actually I'm pretty satisfied with the my stone. But I would like to have the performance a little bit more improved
Is this only for CM6 or what?

thanks for the nice script
fantastic job - works great on my CM6 MS.
Can somebody upload the neccesary files for make it work...
And some instractions please....
I suppose all have the "echo" file in system/xbin. So as i understand we need the "sysctl" file to put it in system/xbin and the propiate script...
So if everyone could upload these 2 it would be nice...
Thanks
Edit: Sorry "sysctl" file already excists in my /system/xbin....
So i have to create a script file without the .sh extention and put in in system/etc/init.d right?
Yeah, I'd like to know as well where to put the file... and with extension or without. I got the files needed in the mentioned folders.
I'd like to point out that the tweaks that have to deal with the network connection seem rather pointless for mobile devices. We simply don't have the bandwidth to necessitate giving such functions any more of our (limited) memory. It also appears to cause a sluggish startup.
Removing
Code:
sysctl -w net.core.wmem_max=524288
sysctl -w net.core.rmem_max=524288
sysctl -w net.ipv4.tcp_tw_recycle=1
sysctl -w net.ipv4.tcp_rmem='6144 87380 524288'
sysctl -w net.ipv4.tcp_wmem='6144 87380 524288'
actually yields noticeably snappier performance.

Init.d
(needs ROM with init.d access and busybox, open empty file, insert header #!/system/bin/sh and put these there, save in /system/etc/init.d and name it something like 77tweaks)
1. strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;

echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;

5. battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Auto-zipalign on boot
(needs zipalign bin)
Code:
[url]http://forum.xda-developers.com/showthread.php?t=860586[/url]
13. Loopy Smoothness tweak
Code:
[url]http://forum.xda-developers.com/showthread.php?t=1137554[/url]
[url]http://forum.xda-developers.com/showthread.php?t=1205744[/url]
14. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
15. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
16. OOM groupings and priorities tweaks - SuperCharger
Code:
[url]http://forum.xda-developers.com/showthread.php?t=991276[/url]
GPS.conf
(create or edit your /system/etc/gps.conf with a file manager with root access)
For improving GPS lock time and signal.
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Other tweaks or guidelines
1. Patch your hosts file for blocking Ads
(please think before doing this; many developers are supported through this way)
Code:
You can use AdFree application for this or changing manually your hosts file.
Here are some databases:
http://www.mvps.org/winhelp2002/hosts.txt
http://pgl.yoyo.org/adservers/serverlist.php?showintro=0;hostformat=hosts
2. Use CyanogenMOD's APN list file - it's one of the most complete.
Code:
It's located in /system/etc/apns-conf.xml
3. Use UOT kitchen for basic theming on your device.
Code:
http://uot.dakra.lt/
4. Use Google's dns servers
Code:
Create an empty file, name it resolv.conf and put there these 2 lines:
nameserver 8.8.8.8
nameserver 8.8.4.4
Save to /system/etc/.
5. Update Superuser and su binary to latest version (3.0 beta)
Code:
http://goo-inside.me/superuser/
6. Disable sync feature in sqlite
(author: ownhere - needs a source for your device so you can compile the /system/lib/libsqlite.so)
Code:
Patch file here: http://forum.xda-developers.com/showthread.php?t=903507
7. Do not use task killers.
Alright, I think this is it for now.
If you have any other tweaks or better values, you can PM me and I'll include them.
Wow... Neojn, will tis work on lg optimus one? I know u used to have a optimus one...

If I have time in the future I can create a script that applies them all.
(with a check of already existing tweaks / compatibility with the device, etc)
If some script fail it may cause bootloop? And can use for all device?
thanks for answer.

None of them should cause bootloop, at least if you follow everything I wrote.
Yes, they work on most devices. Just read what it needs.
how do i test this one because i cant remember what i rename the bold parts to lol
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache

I hav another question..What is "Flags"?
- 18. Miscellaneous flags
- 7. Flags blocks as non-rotational and increases cache size
thanks for answer

It's like it says, you need the /dev/block/ path to system, data and cache partitions.
And they need to be formatted to ext4 of course.
This varies from device to device, whether it is emmc or mtd.
Running the command "mount" should give you the answer for both.

As a noun it's like a property, as a verb is like defining.
Either way, I think I may have some time during next week to make a script to deploy these tweaks on most ROMs.
thanks ya knzo.
thanks . If you have time it would be awesome if you make a zip that can be flashed to CWM
I need a little help creating the script files. I dont need all of these tweaks. So, I need instructions on how to create the file with only what I need.
Can I create just one script file for all the tweaks or do they have to be seperate?

Ok so the reason why I made this topic is because Coertmans asked me about virtual ram in android (2.3.6), which is available in CM9, so I went surfing on the interwebs to find about this zRam, first thing I found was this:
Site: http://code.google.com/p/compcache/ (ramzswap_32a.ko/ramzswap_32b.ko)
Instructions: http://code.google.com/p/compcache/wiki/CompilingAndUsingNew
This is the link to the zRam modules for linux kernels, as I'm not sure if it's able to import it into GB I continued searching and found a GB ROM (CM7) which has zRam. I downloaded the rom and searched for the files that possible could be the zRam. All ram/swap related items I got are these:
in /system/etc/init.d/07script
Code:
ZRAM=`ls -d /sys/block/zram*`;
for z in $ZRAM
do
echo 256 > $z/queue/read_ahead_kb;
echo 0 > $z/queue/iostats
done
if [ -e /sys/kernel/mm/ksm/run ]; then
echo "Kernel Samepage Merging support ON for RAM managment speedup."
echo 1 > /sys/kernel/mm/ksm/run
fi
ZRAM=`ls -d /sys/block/zram*`;
for z in $ZRAM
do
echo 256 > $z/queue/read_ahead_kb;
echo 0 > $z/queue/iostats
done
in /sdcard/gscript/swapon.sh
Code:
echo "Enabling SWAP Now! Please Wait."
echo "OFFLINE"
free | grep Swap
swapon -a

About SWAP!
ROM will activate 3 kind of swap
It's will turn ON (only if you have already created swap file on partition, or set partition for swap (the hard way) )
SD-EXT SWAP
SD-SWAP
EXT dedicated SWAP partition
***If you have SWAP already, or EXT or SD-SWAP/EXT-SWAP, no need to run the swap activation scripts.
***I have created 2 scripts for disabling SD swap before use of USB storage.
I have put them in your /sdcard/gscript
so you only need the app (gscript light or full)
then load this scripts, when you need usb storage run swapoff script. when done run swapon.
or you can install dual mount app. i can’t live without it so try it.

SD SWAP THE EASY WAY!
In Easy way Swap you don't need to reformat or even reboot your phone to create swap!
If you installed my ROM and you don't have swap but you want to stay on HIGH END ROM,
Then you can do this to enable SD swap
Download script sdswap200.sh or dataswap250.sh from my mirror.
Run in in GSCRIPT App or copy it to SDCARD root,

So what do you guys think about it? It seems to me that this is really possible on GB
This is what I tried so far:
Code:
adb shell
su
mount -o remount rw /system
busybox dd if=/dev/zero of=/sdcard/swap bs=1k count=250000 > /dev/null
busybox mkswap /sdcard/swap > /dev/null
echo "/sdcard/swap swap swap" >> /system/etc/vold.fstab
echo 50 > /proc/sys/vm/swappiness
swapon -a
Now I don't get an error, but also nothing seems to happen, I'm going to try to make the sdcard "swappable ready" the manual way now
edit: Hmm I can only pick my internal sdcard for partitioning the sdcard, someone knows how to do that for external?
And how can I see if the virtual ram is actually working?
btw here is the mirror with the files I used: http://www.bourseanalyse.fr/dorimanx/
btw, totally of topic, but I saw 2 cars on fire so I made a video

The easiest and the only way i know of to check how ram, swap, and memory is used is by going into Terminal Emulator and typing in "free" and click enter... (without the quotations)

Ok thanks, used: "free | grep Swap" seems it's not working yet.
Hello
do you know the app swapper2 ?
it do the same what you try to do here !
But in the german forum there are some people who bricked their device with this app so i just want to say that you really have to pay attention with swapping

they bricked it because of partition of internal sdcard If all of us will partition internal sdcard we have more than 50% chances to brick our device. It seems that partioning internal SD affects the 1-8 boot partitions (dunno how to explain it better) I`ve just woke up lol
Also we need a kernel that supports swap
And we don't have such a kernel

if u are getting all 0's in swap then it is not working... i thik you can try going thru htc dream (G1) gingerbread roms.... they used swap and zramk a lot... well it was essential for the rom to run on that device
If it looks like this (with zeros in the swap line), you do not have swap/compcache:
total used free shared buffers
Mem: 97932 96640 1292 0 272
Swap: 0 0 0
Total: 97932 96640 1292
If it looks like this (with anything other than zeros in the swap line), you do have swap/compache:
total used free shared buffers
Mem: 97932 96004 1928 0 332
Swap: 24472 0 24472
Total: 122404 96004 26400
I had a swap partition on my galaxy 3 and i just wanted to say that it isnt fun...it makes the phone laggy cause you can never have a sd-card which is as fast as a ram module
Sent from my GT-I9001 using XDA
Yes! SDcards even class 10, ain't that stable. Anyhow what's the big deal ?
we never fall short of ram on our device.
Had tried ram swapping on my I9003 and i managed to screw up everything,made it a paper weight (Hard bricked it).
Had to get the board replaced from samsung, on the good side i got the latest latona board with 16gb onboard memory
but i no longer have the i9003
I tried swap while I had Galaxy 3 (it only has 256MB RAM) and I didn't like it. Also many other people reported that it was only slowing down system (even with class 10 cards) SD Cards just aren't fast enough to be used as a RAM...plus, Android is based on a though that free RAM is wasted RAM, right? 512MB for our phone is enough for me, and I've never fallen short of RAM..swap is not needed..but that's just my opinion
I'm not going to continue on this anyway, making your sdcard a swap drives really ****s it up, when I tried to install an app my phone shut down..
Let's customize our ROM.
This thread's goal is to make you understand better about your ROM, how to maintain it, and how to modify it to satisfy your desire. this thread is based of this thread http://forum.xda-developers.com/showthread.php?t=1590330 which I've write several months ago. however, our system is a lil bit different with the one in SGY. this thread will contain more specific information about ICS based rom especially the xperia phones.
I'll made this thread into several section. the first section will explain about the file structure in our system. the second one will tell you about app/system modification, and the thirdth one is about tweaking.
1. KNOW BETTER ABOUT YOUR SYSTEM
1.1 SYSTEM STRUCTURE
first of all, when I said "system" here, what I mean is all the stuff under your system partition. if you're browsing with your file explorer, it's all the files inside /system folder. please don't mix it with a complete android system. if you open your /system folder, you'll find these folders.
1. app : contain all the system's app and the odex file of system app
2. bin : contain the command and bin files for the rom
3. vendor: specified vendor system. you have your specific vendor's app, libs, and config files here.
4. etc : additional setting and files for the rom.
5. font : the fonts
6. framework : system's framework files and the odex file for framework
7. lib : drivers, modules, kernel related files for the rom
8. media : media files-ringtones, notification, bootanimation.
9. sd : folder created by a2sd darktremor. (only modified rom have it)
10. usr : files needed for keyboard, bluetooth, etc.
11. xbin : additional command and bin files (busybox is usually installed here)
12. build.prop file : contain your system default prop
13. ts.conf : a configuration file for your system. you'd better stay away from it.
1.2 DEODEX VS ODEX
Most of custom rom available is deodexed rom while our stock rom is half deodexed rom. I'll try to explain it in most simple way. First of all, we should understand that mostly every app in android consist of three part, *apk files, *dex/odex files, and lib files.
ODEXED rom means that *dex file needed to run the app is extracted from the apk file and placed in same folder with the apk files (/system/app). the positive side, it consume less internal memory and a execute faster. the negative side, it makes the app uncostumizable (cannot apply custom themes) and need more space in system partition.
DEODEXED rom means that *dex file needed to run the app is extracted from the apk file and placed in /data/dalvik-cache. the positive side, the app can be themed (full customizable) and consume less system partition. we could put more app in /system/app in deodexed rom. the negative side, it consume a lot of internal memory. please be cautious with the internal memory space if you use deodexed rom. (NOTE: if you start from stock rom, you may use dsixdia to convert odexed to deodexed rom).
2. APP/SYSTEM MODIFICATION
basicly, you modify your system in two ways. push a file to add/replace file into your system and modify your files with file explorer. it can be done in several ways. if you want to modify your system, you should remember these stuff:
1. file compatibilty : if you push a file, especially some apps, you should make sure that file is compatible with your system. some app require different framework, additional libs, and some other dependencies. make sure you already had all of them in your system.
2. correct file permission: some file don't need special permission. however, some other file require special permission like execution.
3. system free memory : you have limited system partition size. you can't put everything inside it. please be aware with the system partition size and the free memory.
4. always backup before doing everything.
2.1 ADD MORE APP INTO YOUR SYSTEM
it can be done in two ways. the first one, you can add that app into /system/app. the second one, you can add that app into /system/vendor/app. both of them works on xperia's phone. most of the files inside inside /system/vendor work just like in /system. so, if you have an apk in /system/vendor/app, it's not different with having that apk in /system/app. nevertheless, all file in /system/vendor is more prioritizied than the one in /system. it means, if you have two file with same name, the one in /system/vendor will be used instead of the one in /system.
please note that. this trick only work for anything under /system/vendor/app, /system/vendor/etc, and /system/vendor/lib. for an instance, if you create /system/vendor/framework, it won't recognized by system. this trick will usefull for you if you want to modifying your system without touching your original system files. you'll also easiliy distinguish your modification and easily remove it from your system without worying about bootloop.

2.2 CREATE THEME FOR YOR OWN ROM
simple theming stuff could be done by replacing the pic files inside the apk, especially framework-res.apk in /system/framework. a hardcore theming need apk modification. this thread doesn't recover about this stuff since it's too long. please search it by yourself if you interested about it. for a basic theme, you need to modify systemUI.apk and framework-res.apk. the systemUI.apk contain your statusbar. the framework-res.apk contain your system interface.
3. TWEAK UP YOUR ROM
there are a lot of tweak. I'll divide it into two categories. scripts and props. scripts, is a tweak run by specified script. this tweak only work if you have a rom with init.d support or you're using script manager app. most of these stuff can be found in /system/etc/init.d/.
props, is a file contain your system properties. the famous one your build.prop inside /system. aside of it you actually have default.prop but this file is stored in your ramdisk and can't be modified without kernel modification. you have a lot of method to modify your prop stuff.
1. modify your build.prop file. you can put your own prop or modify the prop value inside this file. seems easy, but this is the most risky one. you can brick your device easily if you're not carefull when modifying it. I don't recommend it for new android user.
2. create a file "local.prop" in /data. the less risky method. it works just like when you modify your build.prop directly. however, it's less risky since if you got bootloop, you only need to delete it and your device will revived. I always prefer this method for my rom modification
3. create script in init.d. the basic form will be
Code:
#!/system/bin/sh
# the custom prop
setprop <prop key><space><prop value>
for an instance, if you have a prop in your build.prop "dalvik.vm.heapsize=128m" you can type "setprop dalvik.vm.heapsize 128m" in your script. this trick is usefull if you're a rom modificator and want to install something which require specific prop. in this way, you don't need to know anything inside build.prop/local.prop. you can make an universal mod which can be installed on a lot of device. bravia engine mod works fine with this method.
BONUS FOR TWEAKERS
if you have time, you can rewrite all the stuff by yourself to avoid double typed script with different value. its easy but need a lil more patience. I'll try to give quick explanation. our tweaks mostly work via init.d script. the basic structure will be.
Code:
#!/system/bin/sh --> the header. tell the system to use "sh" command on the script below
echo bla bla bla. --> the script
I'll differentiate the scripts into two parts. the one run a bash script and the one used to change our device setting. the first one is quite complicated and usually written on separated file. the famous one might be zipalign script and sqlite script. basicly you only need to add the script and the required files (the libs and the binary file in /system/bin) into your system and need no modification. just add and leave it.
the second part is the one used to change our device setting. we can differentiate this stuff into two things. the setprop stuff and the "other stuff". the setprop stuff is quite easy to use. the setprop stuff basic form is "setprop <key> <value>" for an example:
Code:
setprop ro.ril.enable.dtm 1
setprop ro.ril.gprsclass 10
setprop ro.ril.hep 1
setprop ro.ril.enable.3g.prefix 1
setprop ro.ril.hsdpa.category 8
setprop ro.ril.hsupa.category 6
setprop ro.ril.hsxpa 2
setprop ro.ril.enable.a53 1
some of these script written in form of "setprop ro.ril.hep=1". that's the wrong way. the correct way is as I've described above.
the second part, the "other stuff" work in three different way. for an example, look at these files
Code:
/proc/sys/kernel/shmmni
/proc/sys/kernel/shmmax
/proc/sys/kernel/shmall
these files have certain value on it. if we want to change the value written on it, we can use three different way.
1. use "sysctl -w <key>=<value>" form. in your init.d script you'll type
Code:
sysctl -w kernel.shmmni=4096
sysctl -w kernel.shmmax=268435456
sysctl -w kernel.shmall=2097152
2. use sysctl.conf file. in your sysctl.conf file, you'll write
Code:
kernel.shmmni=4096
kernel.shmmax=268435456
kernel.shmall=2097152
while in your init.d script you'll write "sysctl -p".
personally I prefer the number 1 since I can made a simple test to check whether if the script is running or not and add it into my log files. anyway, these trick only work for the files under /proc/sys. if you want to change the value of different files, you'll need to use method number 3.
3. use echo command. the form is "echo "<value>" > /path/to/file". in your init.d you'll write
Code:
echo "0" > /sys/module/lowmemorykiller/parameters/debug_level
echo "64" > /sys/module/lowmemorykiller/parameters/cost
echo "0,1,3,5,7,15" > /sys/module/lowmemorykiller/parameters/adj
echo "4096,5182,6400,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
to avoid double typed script, we can categorize our tweak into several group. I'll show you my tweak as an example. you can learn it or start with it. I don't take credits, so that you can modify it anytime without asking my permission.

my own made akuro script. it works to move dalvik-cache,app, and /data/folder from our internal memory to ext2/3/4 partition on our sdcard. it will save our internal mem space. sadly this one is for samsung device. you need to modify some part of it.
have a nice tweaking
EDIT: btw, for my first and second tweak, you should use your own value. my value is taken from sgy and still under investigation to get better result.
as I've promised I'll tell you how to build your own rom. however, I made this thread for someone who started to build his own rom. I want to made this post understandable even for a newb in android world. this guide doesn't recover stuffs like how to customize the theme or add more feature into your your rom. that one require a lot of resources and you need to learn it by yourself.
the first thing you need is the system files. you can get it by dumping your system partition, modify an existed rom of even build it from scratch by yourself. assume if you already have one, the next thing you should learn is the updater script.
basic rom installer structure will be something like this.
1. meta-inf folder : contain updater script and updater binary to install your rom
2. system folder : contain your system files
3. additional files and script.
for a start, you can get meta-inf folder from here http://www.mediafire.com/?nxgiz0993brp9re
it contain a basic updater script to install a rom. it designed to install a rom for another device. you need to modify it if you want to use it.
if you open the updater script, you'll see this

lets breakdown the updater script. basic updater script contain several parts. from above script, we can divide it into these parts:
1. UI SCRIPT
it will give you information about your rom installation.
it consist of two part. the first one is the ui_print, it used to show some text when you install the rom. for an example, ui_print("Welcome to MySs Rom "); it will print Welcome to MySs Rom on your screen. the form is
Code:
ui_print("<your text>")
the second one is the show progress stuff. for an example show_progress(0.5, 20);.the form is
Code:
show_progress(<the progress part 0 to 1>, <time needed to reach progress part>);
if you look into the example, it means that the installation progress bar will reach 50% in 20 second.
2. INSTALLER SCRIPT
the most crucial part. it install the files into your system partition.
it consist of three part. the first one is the mounter script. it used to mount a certain partition when you install the rom. this is one of the example mount("ext3", "EMMC", "/dev/block/mmcblk0p2", "/system");. the basic form is
Code:
mount("<partition file>", "<partition type>", "<partition location>", "<place where it mounted>");
the second part is formater script. you can do it by format the entire partition or simply delete all the files in the partition. I always choose the second one to avoid getting a corrupted partition. the basic form is
Code:
delete_recursive("<folder address>")
# or in an example
delete_recursive("/system");
the last part is the one used to copy the files into your system. you can do it in two ways. the first one you copy the files one by one. you'll use something like this.package_extract_file("installbusybox", "/tmp/installbusybox");. the form is package_extract_file("<file name and address>", "<where you want to copy it>");. the second one is you copy the entire folder. you'll use package_extract_dir("system", "/system");. the form is package_extract_dir("<folder name inside your zip file>", "<where to copy it>");
3. MODIFIER SCRIPT
to change the permission you'll use
Code:
set_perm_recursive(0, 2000, 0755, 0755, "/system/bin");
# if you want to change it based on the folder
# basic form
set_perm_recursive(<1st owner>, <2nd owner>, <folder permission>, <file permission>, "/system/bin")
set_perm(0, 3003, 06755, "/system/bin/ip");
# if you want to change it file by file
# basic form
set_perm(<1st owner>, <2nd owner>, <permission>, "/system/bin/ip")
to create symlink
Code:
symlink("toolbox", "/system/bin/ls");
# basic form
symlink("<the file name>", "<the link name>");
4. ADDITIONAL SCRIPT
it mainly use to run certain script. for an example
Code:
package_extract_file("installbusybox", "/tmp/installbusybox");
set_perm(0, 0, 0777, "/tmp/installbusybox");
run_program("/tmp/installbusybox"); [code] first thing you should remember is that you need to extract the script first. in this case, is the installbusybox file to /tmp. to run the script you'll need to change the permission and run it with run_program. the basic form is [b]run_program("<the file>")[/b]
[/hide]
now, after you know about the updater script, you need to create the proper updater script for your rom. the basic script will be.
1. mount all needed partition. some rom installation need to mount /data, /cache, etc. make sure you already mount all of them
2. delete all the old system files.
3. copy all new system files into your system.
4. change the owner and the permission of certain files and folders. make sure you have the exact owner and permission setting of all the files copied into /system. the default is owner: root. permission: rw-r-r.
5. create symlinks.
6. run the additional script.
the last step, pack all the files into a single zip file and install your rom. enjoy your rom.

Init.d Tweaks
(Needs ROM (Kernel) With init.d Access And Busybox, Open Empty File In Text Editor (Notepad ++ Or Similar), Insert Tweak You Want In Header,Save in /system/etc/init.d and name it Lomething Like 73tweaks)
1. Strict minfree handler tweak
Code:
echo "2048,3072,6144,15360,17920,20480" > /sys/module/lowmemorykiller/parameters/minfree
2. Internet speed tweaks
Code:
echo "0" > /proc/sys/net/ipv4/tcp_timestamps;
echo "1" > /proc/sys/net/ipv4/tcp_tw_reuse;
echo "1" > /proc/sys/net/ipv4/tcp_sack;
echo "1" > /proc/sys/net/ipv4/tcp_tw_recycle;
echo "1" > /proc/sys/net/ipv4/tcp_window_scaling;
echo "5" > /proc/sys/net/ipv4/tcp_keepalive_probes;
echo "30" > /proc/sys/net/ipv4/tcp_keepalive_intvl;
echo "30" > /proc/sys/net/ipv4/tcp_fin_timeout;
echo "404480" > /proc/sys/net/core/wmem_max;
echo "404480" > /proc/sys/net/core/rmem_max;
echo "256960" > /proc/sys/net/core/rmem_default;
echo "256960" > /proc/sys/net/core/wmem_default;
echo "4096,16384,404480" > /proc/sys/net/ipv4/tcp_wmem;
echo "4096,87380,404480" > /proc/sys/net/ipv4/tcp_rmem;
3. Vm management tweaks
Code:
echo "4096" > /proc/sys/vm/min_free_kbytes
echo "0" > /proc/sys/vm/oom_kill_allocating_task;
echo "0" > /proc/sys/vm/panic_on_oom;
echo "0" > /proc/sys/vm/laptop_mode;
echo "0" > /proc/sys/vm/swappiness
echo "50" > /proc/sys/vm/vfs_cache_pressure
echo "90" > /proc/sys/vm/dirty_ratio
echo "70" > /proc/sys/vm/dirty_background_ratio
4. Misc kernel tweaks
Code:
echo "8" > /proc/sys/vm/page-cluster;
echo "64000" > /proc/sys/kernel/msgmni;
echo "64000" > /proc/sys/kernel/msgmax;
echo "10" > /proc/sys/fs/lease-break-time;
echo "500,512000,64,2048" > /proc/sys/kernel/sem;
5. Battery tweaks
Code:
echo "500" > /proc/sys/vm/dirty_expire_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_centisecs
6. EXT4 tweaks (greatly increase I/O)
(needs /system, /cache, /data partitions formatted to EXT4)
a) removes journalism
Code:
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
b) perfect mount options
Code:
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier=0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,nobh /cache
7. Flags blocks as non-rotational and increases cache size
Code:
LOOP=`ls -d /sys/block/loop*`;
RAM=`ls -d /sys/block/ram*`;
MMC=`ls -d /sys/block/mmc*`;
for j in $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "2048" > $j/queue/read_ahead_kb;
done
8. microSD card speed tweak
Code:
echo "2048" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
9. Defrags database files
Code:
for i in \
`find /data -iname "*.db"`
do \
sqlite3 $i 'VACUUM;';
done
9. Remove logger
Code:
rm /dev/log/main
10. Ondemand governor tweaks
Code:
SAMPLING_RATE=$(busybox expr `cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_transition_latency` \* 750 / 1000)
echo 95 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo $SAMPLING_RATE > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/sampling_rate
11. Auto change governor and I/O Scheduler
a) I/O Scheduler (Best: MTD devices - VR; EMMC devices - SIO) - needs kernel with these
Code:
echo "vr" > /sys/block/mmcblk0/queue/scheduler
or
Code:
echo "sio" > /sys/block/mmcblk0/queue/scheduler
b) Governor (Best: Minmax > SavagedZen > Smoothass > Smartass > Interactive) - needs kernel with these
Code:
echo "governor-name-here" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
12. Move dalvik-cache to cache partition (if it's big enough) to free up data partition space
Code:
CACHESIZE=$(df -k /cache | tail -n1 | tr -s ' ' | cut -d ' ' -f2)
if [ $CACHESIZE -gt 80000 ]
then
echo "Large cache detected, moving dalvik-cache to /cache"
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# bind mount dalvik-cache so we can still boot without the sdcard
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
else
echo "Small cache detected, dalvik-cache will remain on /data"
fi
13. Disable normalize sleeper
Code:
mount -t debugfs none /sys/kernel/debug
echo NO_NORMALIZED_SLEEPER > /sys/kernel/debug/sched_features
14. GPS.conf
(create or edit your /system/etc/gps.conf with a text editor)
a) European NTP server (replace for america or asia in your case)
Code:
NTP_SERVER=europe.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
b) SE supl for A-GPS (better than Nokia's or Google's)
Code:
SUPL_HOST=supl.sonyericsson.com
SUPL_PORT=7275
Warning: Using these tweaks may brick your device. Use it with caution.

Install Universal Init.d from Play Store and follow in-app instructions. Init.d support will be enabled on your device. Your device must be rooted first.

I make and init.d script and i copy your custom values to my init.d script. However, on net speed tweaks, the tcp_rmem and tcp_wmem didn't change the value at all even i edited it. Any help?
Should it be in text file or script file?
So we create a different text document containing each code for each tweak?? Not all In one document in the init.d folder??
Nice write up, bro. Thanks. Will have to try.
Guys so why aren't these enhancing tweaks and buildprop tweaks already available in our phones? Why aren't our phones optimized?
Tweaks good for one person or situation are not necessarily optimal for every case in general .

Can you help please?
Hello, I'm a newbie here. I wish to overclock my stock kernal, So it can be done through tweak? or I have to compile new overclock kernal from stock kernal source? Their's already a overclocked kernal for my device but its for cm11 and i want to use it on 4.1.2 JB stock ROM. Is their any simple way out?
Your help will be appreciated. Thanks .
use cm11 for s7392 or try
cm12 new developed

Thanks for suggesting new Cm12 kernal.
As of cm11, X264 encoding is important for me, plus their were some other minor bugs in that build. Though i agree its the best build compiled rom for Trend.
I will myself start some project after June~July.
What happened to your device though? You are among the few members who are guiding peoples on threads related to this device and i really appreciate it.
