Hello,i am new in this community
i am little confused how to change swapiness in my mini?should i change it in terminal?
curently i am usinig S2E, and a 256 mb swap partition.
download swapper from market it have the option to set swappiness in the setting but choose the swap partition instead of swap file

ok so i made a linux-swap partion on my sd card that is 64mb. Now do i need to activate it somehow? or does cynogen do it for me? i tried to search but couldnt find. also do i need update my radio? it is 2.22.19.26I
You need user.conf and userinit.sh files on your ext partition. There's a guide on how to set that up here.
ok and can i have compcache and linux-swap at the same time? or do they do the same thing? also do i need to make a partion for compcache? and i cant find the htc keyboard in 4.2.3.1, does it come with it?
i thought if you have 4.2.3.1 you didnt have to add the files as it does everything for you? am I missing something.
is compcache and linux swap the same thing? and do we need both?

lol, no.
Swap is virtual memory. It uses a seperate partition to act as extra RAM, but it's nowhere near comparable to real RAM.
Compcache compresses what's in the RAM, so there's more space to cram files in. The problem is constantly compressing and decompressing files in RAM puts a heavy strain on the CPU.
so do i need to put the usernit files on or did this rom already do it?
does anyone know how to use the user.config app to do this?

You DO NOT have to add any user int files to your sd for swap to work.
Its already rolling if you installed correctly.
go to terminal and use the print command to view your allocated spaces for each ext
Better yet, use the "free" command to see if it is really being used. I am pretty sure Cynanogen does not use a swap partition by default. It needs to be enabled. A easy way to check and setup your swap it to download swapper.
When I type free in the terminal I see 0 for total, used and free swap. I made an ext4 and a 32mb swap partition on my sd card. How do I enable swap on Cyanogen 4.2.5?

So I have a 96 MB swap partition nd I used this app called swapper to turn it on and I have two questions one is how do I know if the swappiness thing worked like is there a command I can put in terminal to check and there's an option called swapiness underneath swap file size so what should I put there and I know I don't need to specify a swap filze size beçause I'm using the partition

"free" enter
or go into the swapper app and click on "Get Information"
thanks! and uh my swappiness is ok at 40 right?

Yeah, 40 to 60 should be okay.
I installed swapper 2 and set swap 256mb for the game, but it seems like my kernel doesn`t support ex 2. I use CM 6.1.0 rc4 and kernel 2.6.32.9-p3 from p3designs. info/kernels/
+ all
CIFS
UFS
XFS
EXT 2/3/4
FUSE
NFS
RAMZSWAP
SQUASHFS
but it can`t create swap file! also i have sd-ext visible in root explorer and when i check to use extended prtition instead swap file it say:
turning swap off partition FAIL
swapoff: /sd-ext/: is a directory
formating swap partition FAIL
mkswap can`t open '/sd-ext/': is a directory
i've installed linuxdx 004 and i'm trying to use swap.
someone recomnded swapper2 and when i turn on the swaping and reboot, i go into the terminal and write 'free' it says it doesn't have swap memory.
do i need to make a special partition or something??
setting it
swap place /mnt/sdcard/swapfile.swp
swap size 128mb
swappiness 10
then turn it on.
wait until it successfully create the swap file.
if not success,on it again
you will see Turning swap off(file) ok
"Its recommend to partition your sdcard before flash"
whats the use?..........
you can use cwm with the phone or minitool partition wizard with the pc

the rom maybe containing a2sd script that's why it need a second partition do it there is no harm
What size this partition should be? 100MB is enough?

atleast 512 mb for ext parttion you should create a swap partition of 256 mb,
swap will replace the ram according to the swappiness set by you

So it should be 2 partitions: one with 512 MB and another with 256 MB... The one with 512 should be formatted ext4? and the other swap (of course)?

Set it as ext2, it's faster.

Here's some info on how Linux (and thus Android) uses swap. http://www.linux-tutorial.info/modules.php?name=MContent&pageid=89
I wouldn't bother with it on a phone since Linux will just swap unchanged files right back to where they are on the phone storage without the need for a swap file and since it's unlikely that you'll ever multitask large user files on it there really is no need for it.

swap is optional but it's good to have

For what? Who is changing large data files on their phone? In all likelihood it will cost you more memory to have a swap file than it will save you memory since it won't be used.
Linux won't use it at all if the file in memory hasn't changed since it was last read from storage, it will just swap it back to where it was last read, that is, if you have an app open and more memory is needed linux will first check to see if the file has been changed since last read and since it's an app it will just link it back to where it was read from in the first place rather than to put yet another copy in swap.

am not talking about swap file am talking about swap partition and if you think there is no need then why are there paid apps like swapper for root and why are people paying for them.
suppose you are playing shadow gun with help of cf3d after the play you find that all the app like launcher background working apps are stopped due to low ram but if you have swap then the app's memory will move to swap partition and it will not close
when I had mini I had a swap partition of 512 MB and it was really working and if you think the life of SD will decrease then you should know that it has a veeeeeery lil effect on life so don't worry there is no harm
Thank u for this useful thread..

Whether you use a swap file or partition is irrelevant, Linux can use either and they work exactly the same.
In your example, all the apps would be swapped RIGHT BACK TO WHERE THEY ARE STORED since they did not change since last read, the swap would be unused and the apps would still be swapped.
I don't know if it's that you fail to comprehend the simple subject or refuse to read both what i post and what i link to but you are not understanding this.
Of course it won't affect the SD cards lifetime, it won't be used.
