I recently bumped into a few scripts like supercharger v6 and killjoy. I'm not really sure what to think of those, but they seem to have a good effect on reducing lag on my phone. Because i'm not sure what they exactly do and think that they might change things which i don't want to be changed (ie. security risks etc) it's a good idea to discuss this and put some information about these together!
The ones i tested were:
Pureperformances -> http://forum.xda-developers.com/show....php?t=2360670
Supercharger v6 -> http://forum.xda-developers.com/showthread.php?t=991276
Killjoy -> http://forum.xda-developers.com/show....php?t=2411161
Ecspecially the last one feels good to me in terms of making the phone smoother and snappier. Even when using stock kernel with standard settings and governors etc.
