The kernel is arguably the most important part of any ROM. A well written kernel makes the device rock stable, battery-friendly, and lag-free. That’s why we have so many greatly written kernels are available here at XDA. But having a good kernel is one thing, and squeezing the maximum performance out of it is another. And without experience and excessive knowledge, it’s sometimes difficult to modify even simple variables.
More than a year ago we informed you about Trickster MOD, a great tool designed to change various kernel settings. Unfortunately, many of functions available in Trickster MOD are available only in premium version of this app. XDA Senior Member xcesco89 created an alternative, fully free application to adjust some kernel values without messing around using adb shell or terminal emulator. With the tool, he made it’s possible to tweak your CPU and GPU, as well as set scheduler and many other variables. If you are planning to play with your kernel, an application like Kernel Tweaker Beta should be tucked away in your drawer.
You can get the newest version of this app and read more about its features in the development thread. We recommend that you exercise caution though, as setting improper values can damage your phone in some extreme situations._________
