All start on boot default for - Dynamic management of timer slack , LowMemoryKiller management of not killable processes Already been removed !
- USE PERFORMANCE CONTROL to enable it > http://xdaforums.com/showthread.php?t=2401988

Code:
Settings of The Available Features
partly been taken from Christopher explanation thread - http://xdaforums.com/showthread.php?t=2172148 all credit go to Christopher83 please thank he for prepare this detail of function

LowMemoryKiller management of not killable processes
This feature allows to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.

This feature exposes four new lowmemorykiller parameters:
- donotkill_proc, is the flag to enable / disable this feature for the processes chosen by the user
- donotkill_sysproc, is the flag to enable / disable this feature for the system processes chosen by the user
- donotkill_proc_names, is the list of process names (comma separated) chosen by the user to be preserved from killing
- donotkill_sysproc_names, is the list of user system process names (comma separated) chosen by the user to be preserved from killing

When the lowmemorykiller needs to free ram, it will first kill the processes not included inside the two process name lists chosen by the user.
If there are no more standard killable processes, then it will be necessary to kill one of the processes included inside one of the two white-lists, to prevent system hangs, slowdowns, etc.

How to customize the white lists of processes to preserve from killing:

On HurtSky's Kernel the feature is enabled by default and the provided processes white lists are the following:
- donotkill_proc_names = "com.cyanogenmod.trebuchet,com,android.inputmethod.latin"
this means that Trebuchet Launcher,stock keyboard will be preserved from killing
- donotkill_sysproc_names = "android.process.acore,com.android.phone,com."
this means that the system process, the phone process will be preserved from killing

1) By using a customized init.d script (the custom value will be always restored after a reboot, if you don't format the system partition)
- Download the script named 80dnkp
- If the file has been saved with .txt extension (stock browser), rename it by removing the .txt extension
- Edit the file by setting your preferred status and processes list
- Copy the new file inside /etc/init.d
- Give the rwxr-xr-x permissions to the file (read, write, execution for owner, read and execution for group users, read and execution for others)
- Reboot
2) By directly editing the files inside /sys/module/lowmemorykiller/parameters (note that set values will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set values will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run these commands if you want to enable the feature

Code:

# To enable this feature for the processes chosen by the user echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_proc # To enable this feature for the system processes chosen by the user echo 1 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc

- Run these commands if you want to disable the feature

Code:

# To disable this feature for the processes chosen by the user echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_proc # To disable this feature for the system processes chosen by the user echo 0 > /sys/module/lowmemorykiller/parameters/donotkill_sysproc

- Run this command if you want to add, for example, Trebuchet Launcher (CM default launcher) and the default keyboard to the processes white list

Code:

echo "com.cyanogenmod.trebuchet,android.inputmethod.latin" > /sys/module/lowmemorykiller/parameters/donotkill_proc_names

- Run this command if you want to add, for example, the system process, the phone process and DSP Manager to the system processes white list

Code:

echo "android.process.acore,com.android.phone,com.bel.android.dspmanager" > /sys/module/lowmemorykiller/parameters/donotkill_sysproc_names

This features currently been disable because normal KSM react more better with current settings

Ultra ksm
UKSM is more optimized and also working for single core systems. using this should give much better ram usage, but at the cost of more cpu usage - ( it seems latest version of UKSM optimized for battery usage also )

In this kernel the UKSM off by default -

How to stop and re-run :

to stop uksm run:
echo 0 > /sys/kernel/mm/uksm/run

for re- run:
echo 1 > /sys/kernel/mm/uksm/run

Redirect to this post if users want to enable it on boot > http://xdaforums.com/showpost.php?p=44606319&postcount=880

This UKSM can be tweaked more by visiting this thread http://xdaforums.com/showthread.php?p=44531620
thanks for @eryzerz for informing this

This features also already been remove from package, you can download it from their official thread

Some Information about TURBO BOOST mods http://xdaforums.com/showthread.php?p=37905307 < for futher information ! Please read !
This quote taken from TURBO BOOST thread ! Credit goes to TURBO BOOST DEVELOPERS

Disadvantages of a NORMAL swap file on your sdcard:
A sdcard is always slower than internal memory
You may NEVER unmount the sdcard or connect your phone to your computer, because you then just kill your swap file – it is the same as pulling out the Ram of your running computer!

Disadvantages of a swap partition on your sdcard a.k.a. HARD SWAP (the one that you all always swap ! ) :
A sdcard is always slower than internal memory
You will need a separate partition on your sdcard
You can connect the sdcard to your computer, but you cannot unmount and remove it without powering off your phone – you would kill your swap space immediately!

Disadvantages of a swap file in RAM - a.k.a. ZRAM:
This reduces the already low RAM memory
Leads to many low memory problems, like sense restarts and lags

TURBO BOOST ! PART
Advantages of 98swap_<partition> (TURBO BOOST MODS) compared to the methods above:
It uses internal memory – so it is fast!
This memory is not available to the user (/cache and /system) – so it does not decrease any space given to the user
It does not use your sdcard in any way – so feel free to unmount and remove your sdcard whenever you like – also without powering off your phone!

Disadvantages of 98swap_cache
None - you name it!

BUGS ?

Some users reported that incoming call abit slower to wake
- this just because updated of suspended , it make the wake up abit slow but it help reducing power consumption

Did not boot for me too. Stuck after Samsung logo. Thank god I back up stock beta 1 kernel.

It suppose to be v2.1 for the latest right? You named it v2.2 there. Is it mistaken for the v2.2 for cm10.1?
