[Q] Swap memory/partition doubt and help!!! - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

my device is LWW running PACman 4.3:laugh: and m using transcend 32GB micro sd class 4....but i am unable to play high end graphic games wich take a lot of RAM like asphalt 8 etc...they lag lyk hell and then exit and come back to homescreen:crying:
so i created a SWAP partition of 500MB using minitool partition wizard..
now i hav two doubts:
( M SORRY BUT BELIEVE ME I HAV DONE MAX SEARCHING OF THIS TOPIC ON GOOGLE AS WELL AS ON XDA...ALL I GOT WAS...CONFUSED )
1. wich one is better.. creating dedicated SWAP partition (lyk i hav done) or using apps lyk swapper wich create a swap file somewhere on the SD card or are they both the same??wich one do you recommend??... do both the above methods damage sdcard?? Also is the damage to the sdcard in the long run more in one of the cases or both are equally same??
2. is just a clarification sounds a bit n00bish:silly: too...after creating a swap partition on sdcard (as i hav done), is using third party apps lyk swapper the only way for the device to detect the created swap partition or is there any other way???if so pls tell me..
once again m sorry for creating a new thread...but i did a lotta search and i only got confused...also if i hav missed out any guide on using swap partition..pls link me to it...
thank u

dont worry bro your right here :good: its the help thread 1st i dont have uch xperience with swap as i never used it bcuz i dindt see a big ''diffrence''
but some things to swap: class 4 is bit low for swap recommended is class 6 or better 8. AFAIK swap partition can more likely damage our sd (this CAN happen, when sth went wrong, but usally it DONT DOES (damage on sd) !!) apps for swap are sver but make sure u have enabled save remount feature. also important if u set PARTION swap u must set it too in an app like swapper2 to use it.. (choose there swap on partition) also swap is a tricky thing more means not better, lokk if u have big swap and swappiness (how much to swap ) this means work for the cpu - more work for cpu means lag. same for size more isnt allways better. u must find the middle for a happy cpu and bit more ram, but there isnt ''THE SOLUTION'' i faced it works diffrent from ICS-JB-STOCK etc., even depends on roms and which tweaks it uses.. (i mean if it uses zram its now double the work for cpu ) also important is a fast r/w speed for sd if its to low it stucks on , means lag for u. (thats why a class 6+ card are recommended)
for game:
i mean the best u can do is to use a clean rom without much junk, also installing 2 or more tweakpacks NOT MEANS system runs better. so take it light other tipps to game:
- set background processe to 4 or 2 or evon 0.
- fligtmode on
- kill all apps bfore start play
- dont overclock as much ucan ( it donsent mean it will run smoother, if cpu is overworked it will simly lag.)
- use gpu rendering.
DONT use taskillers!! (these are only work for system and battery eaters)
- set good and fast govenor, and i/o scheduler when u can, search for a good kernel for game as it will offer u best peformace increase.
hope it helped u a bit

thnx for replyin man...you cleared my mind a bit...:good:
i know class 4 is a bit slow...but now after enabling swap i am able to run asphalt 8 with very little (negligible) lag...
but i dont understand by what u mean "enable save remount feature"??
also what u mean by this

i wil try ur gaming tips...
but i dont know much about governors and i/o schedulers...i'll read and find out..but do they actually make a difference??
and can u link me to any performance tweak threads??i too wil try nd search..:fingers-crossed:
also by ur statement u mean that enabling Zram is of no use??:silly:
yup i agree with u..i too hate task killers...
nd i dont want to risk damaging my phone so i dont overclock

no prob bro :good: yes u must find a middle of use swap but not to much as it will slow down cpu (and whole device)
"enable save remount feature" -> use swapper2 app (free) then go first into settings and set if U USE a spap file (on sd) OR if u USE partition on sd (have to be set to in advaced options.) i mean with this if u see there options they are (called) like this ENABLE IT. ist much safer., alos dont set the swappiness to high
go to settings, performance. there u will have some govenors to choose. govenors are like people thery lazy one may good for battery or there stressy one which give u more performance on battery cost and so on read more about them here :http://forum.xda-developers.com/showthread.php?t=2017715 there really important for gaming as they decide how ur system & cpu.. behavs if its called by an app for power like ur game (make a BIG diffrence) i/o schedulers are sth other but think there only avaiable from JB...
also tell me which rom u have!!!! (stock or not etc.)
to zram: zram are compressed stuff to have bit more ram, but it means also more work (ALL TIME) for ur cpu as he have to copres and decopress files bfore placing/ calling from RAM, and when u use SWAP, zram is useless. as its only for low memory devices which sometimes need more ram i especially didnt use it as my ra is okay and it will only eat cpu & battery, i would say in your case u get performance LOSS as of using bith a same time , as said bfore SWAP means mor cpu work too, then imagne cpu must also handle the zram, + game and system, it CANT BE GOOD! and btw a good (best for game) kernel will gie you more boost than all the mentioned things here bcuz hes the most responsible for calling the hw. (if game needs juice )
overclock is okay but i would not more oc than to 1.1 Ghz or 1.2 this is okay btw i use also 1ghz for normal use
with tweks i mean do some build prop tweaks (i would advice do only some not allways all, bcuz more means not everytime better as u know)
than dont use ''lock home in memeory'' and delete ram scripts from init.d folder in system/etc
set a good sd write read speed using some market app. like 1024 or 2048.
a good thread for some tweaks is '' project fluid'' by spex :good: its simple and well working on mostly all roms aslo it contains a tweaked adreno config..
just try some bit around, and tell me which rom
peace

i already told in 1st post...am using PACman 4.3 (build 825)...
BTW unfortunately for JB 4.3 there is no gaming kernel

Okay sry bro was in a hurry so excuse bad englisch bfore, let stake it short
Use only swap no zram, allow the system to give RAM, use sio as io sheduler, as govenor for perfirmace use interactive, smartassh3, or performance this will kepp cpu at highest value.
If u want attach ur build.prop and i take a look for u.
Checks init.ds. And suoercharger makes gaming not good...
Did u use greenify,bro?
Also sry for not recognizibg that u mentiond rom,sry..

I doubt swap will help ...
Mostly it will crash again even with swap ....
Post the logcat when you play the game and it crashes... We will see what happened ...
