Hey all! New to Android (but not cooked roms - winmo mostly). Have noticed that my MT3G is running REALLY SLOW fairly frequently (despite killing apps quite a bit). I'm running Cyanogen's 4.2.2 with APP2SD (ext3 partition). I believe APP2SD may be the culprit but I am not sure. Need a bit of help understanding how this works? Does it create a swapfile + storage for apps, or is it storage only? Any help is appreciated!
do you have a class 8 micro sd card? and do you also have the 32mb linux swap partition along with the ext3?
It is not a class 8, I think it is a class 6 if I am not mistaken I can check (possibly a 4 but definitely not less than 4). The swapfile partition, it is an ext3.

You really don't need a2sd on the mt3g since it has plenty of internal memory. However, a2sd shouldn't be the cause of your slowdown as a class 6 sdcard is faster than the internal flash.
If you're looking for speed, you may want to try my ROM, which doesn't use a2sd for the mt3g by default, and is pretty much the fastest android ROM on the planet.

First of all thanks Dwang for cooking that rom *very appreciated*.
AFA the SD card, I checked and could not tell, it could be a class 2 actually (it is the stock card that came with it, and the only thing on it is a large C with a 2 inside of it so I am assuming it is a class 2). So maybe that is the culprit (my Gold Card is actually a class 6).
If a class 6 (or class 8) is faster than the internal memory, would I benefit from having a swap file on a faster card rather than running off the internal memory?
I was tempted to use the Sense UI roms but I was reading than they are considerably slower. Don't care about eye candy as much as speed and functionality. Based on that would the sense UI still be useful to me?
Again, thanks so much for this Dwang (and for those who have taken the time to reply)

If you are using my ROM, then it doesn't implement swap on the sdcard. It implements compcache which is a compressed swap in RAM (this is not internal flash, two different things). In my testing I have found it faster than using a swap partition on the sdcard (others may disagree).

Or, looks like the Evil deed just got rejected by noob... Dwang wins once again, yeah!
In all fairness eViL was just giving me other options and I wasn't too clear about preferring speed (I mist say the eye candy on the sense UI is soooo tempting but given the issues that I am having right now with my apps2sd, i'm a little shy to go that way). So before the noob gets dissed, figure I would set the record straight... now let the flaming wars begin... LOL
SD increase IT
Note: FreeX10 beta4 users have reported it working but the "auto run" does not.
Allows basic adjustments to the SD buffer.
from 128KB to 3MB
This severely boost's SD read rates.
And is alot simpler that having to manually run and configure scripts.
Does exactly the same as the SD speed boost hack.
Has auto run option.
I didn't make the app.
If you have a problem there is another app that may work for you..
But is only available on the market for a few bucks

that's because there's a difference between 2.1 and 2.2. sd increase it will work on 2.2, but not 2.1. this will work on 2.1, but not 2.2.
the best bet is to use the script i posted 2 weeks ago.

No it works just like "flash fire" http://flashfire.org/xe/
Tried and tested micro cache.
It severely eases the stress of the SD
but "sd speed" testing app is not built to test this kind of setup.
data2SD that gives you a BS score.

so it works, but no? or does it not work, but yes?
increasing cache increases performance, period. it's not a "false" performance boost. if it didn't work, hard drives would not have gone from 8mb of cache to 64mb in 4 years and write ahead would not be an option.

That's not the point. The point is you said the sd speed boost, manual script or app, was pointless and gave false results.

No i said the app used to test the speed is flawed.
As it was not designed to test this kind of setup.
It can't give you a 99% accurate reading cuz of the buffer.

how is it not designed to test this set up? all it tests is the read/write transfer rate to/from the sd card. cache or not, should not make a difference.

Due to the way the cache handles data.
It's now actually testing the cache, instead of the SD, the SD just hinders the cache's performance.
If the test was longer "a larger test file" was used then you would get dramatically different read speeds as the cache becomes filled
and the true SD performance becomes evident under stress!.
This **** is logic to me.. not even worth it to explain, consider yourself lucky.

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.

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?

1. You're expecting a link?! Should I pay for it, too? :S
I use a Sandisk UHS-1 64GB. Red/grey theme, works great.
2. Nobody knows your data usage, so it is impossible to tell. As long as you do not use it under Windows (or any other situation in which you'd need the FAT32 partition) there's no chance of overkill since all storage remains available.
Make sure to read up on the data2sd thread itself, because both questions have been answered there already. Without reading, you might get yourself in trouble.

I'm pretty sure the latest data2sd thread states they are using Red/Grey micro SD and even red/gold (for best performance)
red/gold = 95+mb/s performance but they are very expensive and only come in 16gb configs.

check this thread. I've summarized a bit of the info read so far on the full thread.
it seems to me the grey/red sd is the best choice as the transfers seem to cap out at 20mbs for read and half of that for write, which means that regardless you arent going to get much more of an improvement.
However I'm more interested in getting one of these sd cards for Linux as I use my machine as a dev machine.

This is good news thanks! I can still use the internal storage while using data2SD correct? I will get either a red/gold or a red/gray
depending on the answer to the above question.

Yes, the internal storage is mounted as /sdcardi and is fully accessible.
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?

Who have tried it?
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.
