The purpose of this script to allow user to define their own set of configuration in a easier way. You can play with the parameters (user.conf)
to find out what suits you best.
Please check the third post for change log and rom compatibility list
Install using ADB:
Install using terminal emulator
download the file and unzip it to your sdcard
testing via ADB
testing via terminal emulator
Expected output for compcache 0.5
the (system) beside the number means the value is gather from system and user means from user.conf
example out for compcache 0.6+
This is the default user.conf. By default, the 32MB of compcache is enabled.
To enable linux swap
To enable virtual memory configurations
To enable CPU related configurations
some sample configurations
Equivalent user.conf settings to CM 3.9.10+ compcache default settings
Please do not use notepad to edit the user.conf or userinit.sh because you could end up some funny error due to format differences between unix and windows. A good example of unix format compatible editor for windows is notepad++
If you had any problem with the script please post the error log. This way its much easier to identify the problem
If there any other parameters/configurations that you wish to add, msg me! I will try to add them when i got time.
