Great idea Chainfire.
When a user first decided to use a modified/custom/different firmware on their Samsung Galaxy S, they usually go through these steps:
1. Flash with Odin/Kies
2. Flash update.zip for root
3. Flash other update.zip (GPS fix, battery mod, etc) as necessary
4. Do a lag fix.
It took me a few hours and reading through countless posts to see the pro's and con's for each lag fix.
I will try to go through them as succintly as possible, and if anyone needs more explanation you can either click the link or do a search.
Feel free to correct me, this is how I see the lagfix as when I applied and tested it
Before starting, here is the internal structure of non volatile memory (where data persist after reboots) in Samsung Galaxy S:
- 128MB of very fast NAND (some people incorrectly called this ROM)
- 16/8GB of internal SD with 2GB set aside for application installs (this is why you see your internal SD as either 13+ or 5+ remaining, the 2GB shows up as Internal Phone storage)
- your micro SD card (external SD)
The lag is due to the inefficiency of the file system used in the 2GB (/data) partition for applications, stalling a lot of the read/write operation. You can search this for further reading if you want to.
Lag fixes
- MoDaCo's lagfix: Better than stock on old F/Ws but about the same as JM1/2/5 and JP1/2/3
This lagfix uses the 128MB very fast NAND to store your applications instead.
Pro: very very fast applications opening/switching performance
Cons: You are limited to 128MB of apps including built in apps .
- Mimocan's lagfix: Significant improvements in performance which can also be benchmarked. Requires an external SDcard formatted partly in fat and partly ext3 or ext4.
This moves the /data files into the ext3/ext4 partition on an external microSD card
Pros: very fast, lots of storage space for apps
Cons: You will be unable to unmount your external SD card when the phone is on, and you need an external SD card for this to work
- OneClick Lagfix by RyanZA: Based on mimocan but using the internal SD card. Results are better than with basic mimocan and it is a lot easier to install.
This creates a file inside the 2GB partition that is mounted as /data.
Pros: very fast, lots of storage space for apps, easy to install and undo, available in the market.
Cons: if you install too many apps you won't be able to roll back the lag fix unless you delete some apps. Superseded by RyanZA lag fix 2.3 beta
Erroneous free space on Internal Phone storage (/data)
There are still stalls when installing apps, and when accessing android applications database
- CFLagFix by Chainfire: Based on mimocan, approximately the same as RyanZA's fix.
pretty much the same as OneClick Lagfix.
look above for Pros
Cons: There are still stalls when installing apps, and when accessing android applications database
-Voodoo lag fix by supercurio: a new class of total lag fix
Instead of creating a file inside the rfs partition and mounting it as /data/data, the voodoo lag fix updates the kernel so that the the 2GB partition is using ext4 instead or rfs. This gives the best possible lag fix.
Pros: fast, smooth, across everything you do. The way galaxy s should have been in the first place. The best and most consistent lag fix with no remaining lag left that is caused by rfs.
Support with other kernel mods are starting to show: backlight mod, OC/UV kernel
Cons: Incompatible with clockworkmod recovery
I am now using voodoo lagfix beta 4 only

Love the Vodoo color would like to try this as well...they are getting OUTRAGIOUS numbers in quadrant!

the epic doesn't need a lag fix. the quadrant numbers are due to a flaw in quadrant. the lag fix isn't really providing that much better performance (except fixing the lag for phones that need it), quadrant just blows the score out of proportion. Cyanogen was able to tailor an exploit to show this happens on any phone: http://briefmobile.com/cyanogen-demonstrates-quadrants-flaws
as for voodoo color, I don't believe there is a general port yet, but it is built-in to the MixUp kernel.

I have the mixup kernel w/vodoo and love it! I just saw this NFO and wanted a more educated explaination...now I have it!
Forever looking to run faster, just one of my many flaws..never satisfied.
Do love my Epic!!!
Its included in the boss rom and GenuisDogs kernels
Wait a minute? Are you saying that its possible for the voodoo lag fix to be ported to the Epic 4g and thus making this fast phone faster? Am I reading correctly? (I saw on his page that they are planning to work on te Epic as well)
We do not need the lag fix. The lag fix will not make our phone any faster.
voodoo cons: needs more battery than oclf or chainfire's fix
my experience is, that voodoo is less smooth (less means a bit less but its great too - not laggy)

I talked to Supercurio about me porting it before, but we came to the conclusion that it's unnecessary. We don't use the same NAND chips as the other phones, so we don't have to deal with all the lag **** except what's introduced with RFS. And changing from RFS breaks clockworkmod, so I am avoiding it.
All this is nice,but why is nobody talkin about a fix to use whole 512mb of ram instead 324mb?I had MTS3GS with 600mhz cpu and 512 ram and I hate to admit but it was faster than my Epic even with Sence.If someone could come up with a fix to use whole 512mb instead of 324mb then this phone would fly,this is the only thing that hinders this phone.Rest of the ram is used for cache(ramdisk).
What needs to be done is whole 512mb used for ram and fast NAND used for cache.324mb ram is not sufficient to run android smoothly.

I'm trying to decide if you are trolling this thread or if you recently suffered head trauma. Those are the two most likely things that I can imagine would cause someone to say the MTS3GS is anywhere near as fast as the epic.

Yeah man,mytouch slide was the fastest phone I ever owned(with 2.1),i think that having 512mb ram is better than having 1ghz cpu.If Epic used 512MB it would most likely be even faster.
Which I tried explaining to the last dude before that ***** came at me wrong without a reason,but its the intenet what can you do,lol.
Just to squash any kind of confusion in this thread...
In no way is the Mytouch Slide faster than the Epic 4G.

Go to tmobile and use one with stock 2.1 its just as fast as epic.I dont know what they did to that underpowered phone but its fast.It might not be as fast watching videos,loadind games,etc.But android system itself is fast and more snappy then Epic,i compared the two,gotta be extra ram.
Don't take this the wrong way....but if it didn't load games or play movies as fast, doesn't that at least in part make the epic faster?

I recently installed root explorer in my milestone xt720 (dexter's froyo) and i found out that there is more than 100 MB free memory in cache folder, while on the other hand i am running low on memory for my apps and RAM. I barely get 30 MB free with no apps running in the background. This makes my phone really slow even when its overclocked to 1Ghz. So is there any way i can use some of the free memory from cache as RAM or as data for downloading apps? Thanks
Nope. Just nope.
Yup, FJFalcon is right. The idea sounds pretty good. If you could use the internal flash as a swap it seems like it would be much faster than the sd-card swap. But there are too many problems with this idea. First, it that would involve some sort of weird partitioning of the internal memory (which Motorola prevents on this phone -- locked bootloader). Second, on most ROMs with a clean install you get something around 70MB free space on /system and around 130MB free space on /data. So you're really looking at 200MB at most, and that's assuming you don't install any of your apps on the internal space and no cache for any programs. You COULD throw all the apps on the sd-card (Link2SD), but you'd get a performance hit there and then with no cache...ouch. It would get pretty complicated pretty quickly. So I think that's the long answer for FJFalcon's reply.
thanks alot fjfalcon and thejaycan
but as far as ive seen this phone never uses upto 100 MB cache and, using this phone for so long, it gets frustrating seeing all that space wasted!
i wish something could have been done.
Is there a way to use memory in ur sdcard as ram for ur phone, so i can increase the performance. i think u can, so if u now how to can u post a link?
And i am using MikRunny rom

IIRC, there is a mod to use either a partition or a file on your MicroSD card for SWAP space... which is basically where programs that normally reside in ram would go when not in use... think its one by sparksco...
however, I dont see hardly any kernels with it built in these days... its a GOD SEND on my HD2 and Hero... Id love to use SWAP partition on all my devices...
hope someone more knowledgeable about whats out will reply
First this is the wrong thread for questions and answers.
And yes we have a few kernals that allow swap. But the rom as well needs to have that available from what I recall. Think cm uses 128 max though. I know there is a miui rom that uses swap here too. Does come in handy. You will need to reformat your sd card for swap if your going to use it. There is also ext3 and 4 and that acts like available storage space for your phone. I would only use 1-1.5 gb for that though. Some of these big games only want to go on your sd card.

One of our biggest supporters of swap has actually decided it's not such a good idea.
And it does not speed things up. It slows things down. Even with a class 10 sd card.

I was using swap for quite some time and it seemed to work really well for awhile and then started to cause my phone a lot of lock-ups after awhile. I think it was just eating up my sdcard too much. And it has been proven that swap wears on your sdcard quite a bit. I don't think it's worth it. There's a script made by Darkky that patches memory leaks in roms that seems to work good. I include these in a lot of roms and my memory always stays above 80mb.

What people fail to understand is that SWAP or fake ram is INHERENTLY IOPS sensitive... that being said, NONE of the Class 10 MicroSD cards have had ANYWHERE NEAR good enough IOPS for SWAP intensive operations... On my HD2 I went through testing 10 MicroSD cards of different Class's and sizes to find out which gave me the best performance while using SWAP and what gave me the best IOPS, Sadly, out of them all, only a Class 4 and Class 6, where anywhere decent enough to be good enough to function as SWAP devices... I mean 4 other ones worked... but you could tell with these 2....

It makes perfect sense... lets take game files from an SSD and transfer them to a HDD... while RAM and MicroSD both use NAND/Flash memory, its still a medium transfer as well! ERGO if you have a crappy IOPS MicroSD card, your going to notice slowdowns and wait times while things in RAM are swapped out to SWAP and vice versa... I guess the best comparison is using the SLEEP function on Windows 7 VS the Hibernation function...

yeah SWAP eats the CRAP out of your MicroSD card... proven fact... HOWEVER, if your like me, 8GB and 16GB cards are rather cheep these days, I totally dont mind spending $10-30 every 6~ months buying a new MicroSD card if it keeps my OLD device speedy... (pun intended)
I got a link around here that I posted somewhere with like 4-6 different MicroSD test run results... will edit this post and link it later...
Oh, and yeah, this belongs in Q&A... but I cant blame you... its a legacy device... and I only visit the Android development section for any device I use... :X
EDIT1: "halrulez" my HD2 running on the NIGHTLY CM7 builds has ZERO problems using/utilizing my 1GB SWAP partition... its all kernel/romsetup based...
EDIT2: some things I thought I should point out after I re-read my own post... in the Windows Sleep V Hibernation statement, when in Sleep, the RAM is kept on, and thus requires no loading time, in Hibernation, RAM is stored on the HDD/SSD and must be transferred back onto RAM before it will boot... I also forgot that I backup my MicroSD's contents with Dropbox and Box software, as well as backup's that are performed whenever I plugin my Phone or MicroSD to my desktop or laptop...
There are apps like juwe11's ram app, rom toolbox has a memory settings, script manager in combination with v6 supercharger script (which I highly recommend, as it helps prevent sense reloads), auto killer memory, etc. Each phone has a "brain" of it's own. My phone likes v6 or auto killer memory, but other phones like juwe11's ramscript/app. Trial and error. Good luck, and post your results if you want to.

That is a good explaintion. But personally I don't want to be the guy that releases a rom with swap already in it and get the guilt of someone's sdcard breaking. As drob311 said there's apps and other ways of making it work and my rom/kernel does still support these other ways of using it.

you do know that you can enable SWAP in a rom, but make it contained to SWAP PARTITION only? ergo if they made a SWAP partition on their MicroSD card... hence you have zero liability if said card breaks... you have to have SOME knowledge to repartition a MicroSD card properly for a SWAP partition
BTW, I fully support enabling it that way, it also leads the way to making the script for SWAP file vs partition easier because the ROM is ready for it, its just not enabled unless someone inserts the custom script OR has the proper partition for SWAP!

Yes I know. I already had a swap script for swap partition for cm7 but you need a custom cmparts.apk since cm decided to disable all swap on their roms. Plus I didn't really feel like repartitioning my sdcard once it started acting up. I'll probably just make a seperate add-on to flash over the roms for it if people want it.

im cool with that
actually, if someone can get YES/NO in CWM like on my HD2 you can put it all in the rom and they can choose right at the get-go
that being said, you can still use the custom cmparts.apk even w/o using swap partition... not that big of a conflict since if you have SWAP partition it works if not its disabled... only the functionality is present... and you dont have to maintain a separate script/package/whatever...
also, if your SDCard is acting up, use the SDCard formatter do a full format, then use HD low level format tool... or if you bought HDD Regenerator like me, its easy to find the health of your SD Media... but thats a moot matter... and im done talking for the night i think... (well the night ends in 3min... :X )

You can actually use compcache with out swapping to sd. But any swap introduces latency so it negates most gains achieved. So more apps might not get killed off as quick allowing them to reopen faster but forground apps suffer from the latency and compression.

AFAICT non of our kernels support compcache. It's a patch you have to apply to the kernel itself in order to make it work.

I am glad then that I still use my HeroC (with compcache, you can DEFINITELY feel a SPEED UP rather then down ) as my home Read/Music/Browse device... well that and its extended battery and more responsive touch screen... (yes, i know, new update fix's this.. but I aint tried it yet)... Id beg you to include it in your next kernel/rom... but your deadset on not (its like 2WayCallRecording and No2WayCallRecording Kernels for my HD2... lol!)

I was told in a thread that 128 was Max on swap but I'm always willing to try new things. I did come from my old Heroc was a great phone to first start of on, till it took a crap on me.,lol meaning my mother in law threw it in the washing machine. Then my son threw my wifes in the toilet. Was great because of the best buy protection. Loved the old device but the shift is like night and day. Don't really use the keyboard. what is all I would need to do to use more swap? I haven't had any lock UPS what so ever. Class 4 8GB btw.

Who have tried this mod? I believe ive read it before i just cant see the thread, as i remember its called sd swap (but not that sd swap int2ext)if im not mistaken? Is it worth a try? The mod which gives partition from sd card to expand ram?

wow .. i ll tried it sooon ....
more ram ..... hhh more Hd Games
Sounds awesome, but the maximum swap of 256 MB is a dampener! Hope someone tries it on their i9003 and reverts if it works on this device.
Up!

Try Ram expander app. It dioes same job. I tried that app but frankly speaking we must need class 10 memory card to see actual noticeble difference.
I have a class 10 microsd card and am willing to try this on my i9003, however, would like to try it before I buy this app. Can someone point me to a trial version of this app?

Tried the Ram Expander app on my SL and successfully created a 1422MB partition on my class 10, 16GB microSD card. Terminal Emulator confirmed the same. (Total RAM 1.44 GB)
Need to test it on some games though, any suggestions?
@coolcowboy Try Real Racing 3! And maybe..... Temple Run 2 and Subway Surfer!

Dude did the app make a difference..
I used this app,(Ramexpander),for a couple of months and didnt notice any improvement on terms of smoothness in every roms i tried. I think its just a placebo.

Tried it on my 16GB class 10 card, and didn't find any noticable difference. What a waste!
As far as I know, the swap is used to cache some memory, not all... it doesn't matter if you make a 4gb partition for SD to swap, it probably will use a max of 256mb.. the way it works it's to cache some stuff there, so you have a little more free memory in your device... You will probably never feel the difference in any device with more than 256mb of RAM memory... plus... reading the SD is really slow... so I don't think it would make any difference to us...
Yup, swap is a Linux tool, used to augment the existing RAM, by using a partition on a disk to store less required pages from the RAM in that partition. It is slower than RAM, and dependant on your sdcard IOPS (read and write speed).
ZRam would be better, but that's up to a kernel dev to implement.
Whatever happens though, these features are just to improve multitasking, rather than loading large games and giving the device a speed boost.

As in subject. My phone has SwapSD installed (32GB uSD seen as internal memory).
I'd like to use the actual 1.5GB internal memory with Swapper 2 to create a swap space, expanding phone's RAM?
3.0.8 kernel supports memory swapping?
Thanks,
Leonardo.
I think sdSwap is a placebo effect i used time ago and didnt notice any improvement in terms of performance, other thing is Zram included in our 3.0.8 kernels, this is a virtual ram who complements the default ram and i think enabling it can feel a bit of more multitask and performance, for enabling go settings/performance/memory management/enable zram and reboot, to control the swappyness you can use performance control.apk and to see if its working type ( free ) in terminal. Try both methods and decide by yourself, im just only sharing my experience, hope it helps you on your doubts.

Thanks (already thanked with button, too...:good for the answer!
I'm trying zRAM. But I have a question.
In my opinion, SwapSD and Swapper 2 are two completely different apps.
SwapSD is used to swap between phone's internal memory and the MicroSD memory (storage)
Swapper 2 is used to create a swap space (virtual RAM).
So if I want to give a try with Swapper 2, I need to know if 3.0.6 kernel supports RAM swapping... I don't want to brick my SL...

What i want to say with sdswap is what you are trying to do, a partition on sdcard to be used like ram its not the same like sdswap.apk.
Feel free to use swapper2 or other similar apps to do that theres any problem with our kernels i already did it with any problem and any noticeable improvement.
