Phone lags after installing 2.2

After installing froyo, i noticed the phone lags alot more then when it was stock. I have overclocked it to 1ghz. Anyone else having this problem or have a fix for this?

mine actually got a lot smoother after upgrading.. im on 1.2

did you do a data wipe? also clear the dalvik cache via open recovery if you havent dont it

same here. for those who said its smoother, can u please check how long does it take to start a new app, as in how long does it take for the app to pop up from the moment u click the app in the app drawer/desktop to the time the app pops up? on 1.1 its almost instantaneous but on 1.2 it takes about 4 to 5 secs for the app to open.

it will depend if your apps are installed in the internal storage or on the external SD

Try formatting your SD card.

Less then a second to open in my case. I really don't have any problems with the new update. I'm using a class 4. 8gb memory card that was partitioned with gparte. And dalvik cache is still in phone memory.

I had this problem with 1.1b but I only wiped data, i didn't wipe cache or dalvik. When I installed 1.3 I wipe just cache and dalvik and the 4-5 sec delay is gone.

remember that if ypu install a new update for the custom rom you will always need to nuke the dalvik cache.
its due to the rom not being able to repopulate the cache properly. causing slow down in the system

Lag on wanted and dexters
Using Dexter's 1.3 ROM: Very noticable lag even after a full system/dalvik wipe. opening internal memory apps took at least 4 seconds and even with 800MHz overclock homescreens were jerky.
Using Wanted/Dexter's 1.2 ROM: The lag is less, about halfway between the original 2.1 French sbf I had before and dexter's 1.3. Only problem I find now is that some apps (etc. endomondo and tweetdeck) will force close on opening (only did a dalvik wipe for this one). Tweetdeck still gives update notifications curiously.

Also depends on the app. When a app is heavier, it takes longer to load with the specs we have on the XT720. For example, the browser and Trillian start immediatly (and I am on latest version from Dexter btw), but Angry Birds takes about 6 seconds to load. Simply 'cause it's a heavy app. Same for Pig Rush.

overall 2.2 froyo on XT720 runs way faster and smoother than the original 2.1 that it was shipped with.
at least that's my experience

yep, its definitely faster then the 2.1 that its shipped with.
but it may not be faster then the 2.1 with JIT add-on...and that had more ram available as well i think

noo... i had the 2.1 + JIT add on and it was no where near as fast as the 2.2 from Dexter.
running at stock 720 Mhz feels like it is running at 1000 Mhz
back with the 2.1 + JIT i still had to clock the phone to 1000 to feel what it feels now on 720 Mhz
as for space of RAM, use Link2SD, if most of the Apps that you are using are not Apps2SD compatible

Oh ok, i still have dexters 1.2..not on 1.3 yet which is supposed to be faster.
Will using Links2SD free up RAM? isn't it only the internal phone storage which is affected?
I think I have dexters apps2ext because when I flashed the rom i had a ext2 partition on the memory card so it does it automatically. Does that make sense...i'm new to this stuff so correct me if I'm wrong please.
And does that mean my launcher pro home screen and everything else is on my sd card so it will add some lag- even if its a class 6.

Greetings to all! I few days ago I registered and I am with my XT720 and I hope to learn much, and what we can over time help. Now I'm thinking about changing ROM with Dexters, and I read that many people is more fluid with applications, is a great job by him.
When I go to experience them comment how I worked. by the time I have a question, I hope you can help me .... memory space for application installation is smaller? further applications from the SD? all applications remain after install?

no, the nandroid ROM restore will delete all the stuff that is in your phone, so make sure to backup everything before you proceed.
no changes to the storage, you can use Froyo's Apps 2 SD or the Link2SD app in the App section to do the move to SD card
There is a video tutorial on how to do it in the DEV section

Even after clearing data and wiping cache, i still notice it takes about 3 seconds to load apps (and phonebook/contacts) It may depend on the app as there are variance in its capacities.

Well, hi im new and im from mexico. Sorry for my bad english hehe... well...
I just want to say that i had dex rom 1.3 but yes, it's so anoying touch an app icon and have to wait 5 secs to open it, i'm new in this world and i don't know how improve (or what i have to do) for rediuce these time, another thing is the temperature, whit this rom i have arround 31 - 37 °C and 33 - 40 °C when i am under sun... what can i do?
Now i have the wantedrom 1.2, lets see what happen.

[Q] Darktremor Apps2SD 2.7.1 Available RAM verses Total Free

Using GUI for Darktremor Apps2SD on my phone it shows available RAM usually between 40mb and 85mb. Yet, on Total Free - it shows around 294mb of 457mb. How is this possible? I've ran the a2sd reinstall and never had any issues come back. How is this possible?
My phone is VERY snappy. Wow. Thats all I'm saying, but it does get sluggish if it drops in available memory. How do I use MORE of the total memory? Thinking maybe firerat? (this repartitions the internal memory I believe)
Any suggestions or explanations?
Its a Sprint HTC Hero. Rooted. Running aospCMod-20110322 (froyo 2.3.3). Class 6 2GB microSD card. Using Darktremor Apps2SD with swap, and cache on SD card. I am not using Froyo's native app2SD. Just the symlink used by Darktremor.

must be a GUI bug that prevents showing the real memory available. just go to settings> storage and scroll down to the phone memory row. it will show you the real memory available.

Settings > Memory Info Still shows 53 / 190
Sadly it shows me basically the same thing. Available memory / free memory. Thats my confusion. How do I get it to be 190 available memory or am I misunderstanding something.

HI, I'm new to the forums. Mostly I SEARCH & SEARCH & SEARCH again... so I don't have to ask too many questions. However, as I'm new I can't post yet other areas.
You know about 2 things that I want to ask about.
Having aps2sd (DarkTremors) how long did it take to install? You said you did the Cache which I want to do and when I did mine, it seems to have frozen? I reverted back to my backup. It's my public phone and I need it working. Though I could toss the 'sim' back in the old phone I replaced.
I got to test the effectiveness of a Back up which was quite fast. (That's why I'm wondering? Why it was taking so long?)
SO, how long does it take to install aps2sd (Including letting it do it's thing and creat links? 20 30 40 min?)
I've got a Class4 32gb card.
My other question is about the setup of the GUI. Just install the .apk or do I need to do any tweeking to get it functional with the script?
Hope to get a reply here. Thanks in advance. OH, in case it helps, I'm running an Xperia Mini Pro. I did consider waiting for the Xperia Pro but decided I wanted the compactness... it's a nice
daily user and good pocket size.
OH, and of course great price...

I'm running 2.1 rooted, the market app is 2.2 and above, won't show up for me.

u can try manually apply it.
/sys/devices/virtual/bdi/17:1/read_ahead_kb
change the value inside the read_ahead to 2048 or 3072
the italic, im nt sure its 17:1 or 17, something bout 17 im sure. inside got the read ahead
tis method however, change back to default after reboot

I tried the hack. Changed cache size from 128 to 2048. Write speeds stayed the same, but read speeds went up by about 5Mb/s. My SD card is crap tho, only a class 2. I also only tried the one cache size.

How big of a difference is noticeable between class 2 and class 6?........thinkin bout gettin rid of my class 2 16g if it makes a big improvement
Sent from my X10 using XDA App

Pretty noticeable, using a class 6 16gb increases all data retrieval speed eg contacts, pictures, apps on SD etc. Defo worth it.

Using the app i can set at boot
Sent from my X10i using XDA Premium App

there is no init.d on stock x10, so i set the file "99sdcardreadfix" to "run as root" and "run at boot" with "script manager" (free available at market).
The code working for me:
Code:
#!/system/xbin/sh
if [ -e /sys/devices/virtual/bdi/179:0/read_ahead_kb ]
then
/system/xbin/echo "[COLOR="Red"]3072[/COLOR]" > /sys/devices/virtual/bdi/179:0/read_ahead_kb;
fi
3072 was working best for me with the stock sd card.
read: 3,8
write: 73,4
If another value works better with your sd card, just change the red number to what you need

I have a SA32G (32GB) and the best results i got where with the buffer at 3456KB. Let me know if that works for anyone and if you find it helped let me know with a quick click on the 'thanks' button!

for 2.2 roms, you need to edit the script because echo is in bin, not xbin
download and use scriptmanager from the market, it will allow the script to run at boot.
works great on my 2.1 and 2.2 roms.
devs are not including this in their roms and no scripts are needed.

Thanks! That really did the trick for me, I am set at 1024 now, read speeds went up slightly between 6-7 mb/s while read speeds are around 25mb/s. I could get higher read speeds at higher cache but my write speeds would go down

thread carefully
Hi
I just wanted to point out that read ahead buffer is not a real SD card performance booster. It is the way how your OS handles card reading and buffering data. I agree that illusion of speedup is present and large data set can really benefit from big read ahead buffer (like video audio and some others).
If you try other SD speed test applications like "Sst" aka "SD Card Speed Test" changing read ahead buffer will not make a dent because software is not using buffers to test real performance.
In some cases big buffer can really degrade performance because OS is cashing something that was not needed.
So my advice is to thread carefully and make read ahead buffer bigger only if you suffer from dropped frames in video or audio players, games and if you use app2sd.
Real performance boost can only obtained with better SD card driver if possible (custom kernel) and better SD card class 6 if possible. (not all SD card's regardless of class will not work in your device as expected eg. Kingston SanDisc Apacer and others research before you buy)

[DEV] SD Speed Increase (Diego Stamigni)

Hi boyz,
A lot of you probably read, a week ago, or more, a thread by @brainmaster about a method to increase read/write speed of sdcard (more info on his thread).
Few days after I've made a free Android Market App that do the same thing that's explained on @brainmaster thread, but in a very simple mode.
Well, the app doesn't work on some ROMs, or devices, because the system tree is too different. Recently I released the 1.4.1 update, that improve some functions and, I wish, it could work on a lot of devices but I'm now sure.
In this case, I'd like to ask you a hand about that, to translate this app in other languages, or to be a tester, preferably someone that has problem with that one, specially where the app doesn't work in his device.
Join with me and make together a powerful app, only for the community.

Great job its really works. I found such a cool review of SD Speed Increase App here http://goo.gl/mlFlJ
Keep it up.

Added russian language, v1.4.2

Hi, i would like to help you to translate your app in the dutch language. How can i help you?

Ok, no problem for dutch language. Contact me on skype (diego.stamigni) and I'll send you the XML strings file to translate oka ?

umm i believe by doing this your going to burn out your flash faster. It will write in 2mb blocks instead of 128kb blocks which means every write will do 2mb of wear instead of 128k(up to 16x the wear). Also does this make 4k writes faster? or does it make it slower? You should test this on an SD card using crystalmark

Depend if your system has a max value (like 2048) and over it doesn't go.

the app recommends using 2mb which i did. the internal memory went from like 7-8MBps to 10-12MBps, which is a big increase but that was done by membench. Membench doesn't give any good info as in how the test is done so i have no clue if that is continuous or 512k or 64k of 4k. I'll try to format an sd card using windows later and see what crystal mark scores are but i would put a warning saying you are going to cause more wear and tear on your SD card by doing this.(atleast i believe that will cause more wear and tear but i am no expert. It is worth checking into.)
EDIT: running tests with my 16g sd card class 6. I'll post them when i am done.
EDIT: i ran the tests on my sd card using default (whatever that is) and 2048k. As you can see for some reason doing this there is no difference in speed. I do not know why that is but thats what i got. Do you know how to test this in android? membench only does internal memory.

I will be interested to see your results. I wouldnt think this would hurt the cards life span. It has a limitedn umber of read and writes as it is and this isnt doing to increase or decrease the amount of reads or writes, simply make them quicker.
I suppose though you could look at it similar to OCing a cpu as it will decrease the lifespan of the CPU some what.

i posted two tests i did in the post above i formated the cards using default settings and 2 MB block and saw nothing in windows so maybe this fix is with in the internal settings of android OS i guess.....so:
does that actually affect the block size?
Does it cause more wear?
How does this actually change the writing and reading?
Does it only improve sequential? or does it also improve random?
Does it hurt random because of the larger block write?
i think these are some important questions to answer. Also it seems this only affect internal memory and not the SD card. Because i found a boost when using membench which tests internal only i guess and i found no improvement using sd tool testing my micro sd card. Does anyone have any input on this? I think there are a lot of questions needing to be answered here.

great app.
can you keep option for 128k? (it is there in previous version, but not in latest one)

There has been two updates on the market for your app BUT no change log of updates.
so what has been changed? also this has ads in it so is it just to update the ads or is it an app update?
Also is there a donate version with NO ads. This i think is a must now-a-days.
Linda Manager file manager will tell you if an app has ads and it's free on the market and the paid app has NO ads.

Okay to somewhat answer this persons posts. and to inform unawares.
1st read the research post referenced in the OP.
the block size is the same, it only affects how it reads and not how it writes. therefore additional "wear" would be neglible at the most.
since its read ahead, its not going to have much of an effect on random/small files.
also its not an internal android setting. judging by the location of the setting its actually a kernel setting.
please feel free to correct me if im wrong, and provide a legit link i can learn off of.

Questions ;-P
app is always running in services ^^ so... does it need to edit 'read_ahead_kb at every boot?? i.e. you can't use it to change setting & then uninstall b/c file will revert to default??
++ If set to 2048 kb it makes music skip every so often... So I have mine set to 1024 kb & I don't get this issue

I am using this on an HTC Hero CDMA running CM 7.0.3. Seems to work well, except when I click it to persist the setting upon reboot, it doesn't appear to. After a reboot, the status always shows 128kB. Is it actually adding the script to init.rc to be applied on a reboot?

Sto usando questa tua utilissima app. Solo che ho trovato come valore dello stato a 3072kb mentre secondo la tua app. il valore migliore è 2048kb Non capisco allora come mai sto ottenendo un valore cosi grande?

Is it possible for an update to set to 128? The HTC Evo works best under that setting, and it is no longer an option.

Diego & All,
I am trying to buy this app in the Premium version in the Google Play Store and it keeps declining the Card I always use. I can't purchase anything. Called my bank. They said they're not even seeing the attempts and my Card is Active and fine.
Is anyone else having a problem purchasing this app (or any app) from Play?
I wanted to get it thru Google Play, so it will recognize the purchase in the future and in case there's any updates.

Nice app, whats is the most optimal value for galaxy s with a class 6 16Gb card? Can i expect any corrupt data with this thing?
Sent from my GT-I9000 using Tapatalk

Hi !
It really depends on the size of your files.
Just for example, if you have thousands of small textfiles a higher value doesn't have any benefit for you. If you have bigger files, like MP3-Files or photos, a higher value speeds up your phone.
You might start with 2048kb.
Regards
Akusari

I've tried all values.. 1024 and its multiples.. but my performance hasn't budged even by a margin! read speed stays at 12-13mbps for all values I'm having an 8gb class 4 sd card running on LG optimus one

My SE ARC use 16gb class 4, change from 128k to 4096. Then I run TM backup, the speed are good.
