i propose to you a new tweak for kernel CFS only, that is a little bit different than tweak ch33kybutt's or luismaf's, more for preserve battery.it is for any rom 2.1 or 2.2, CM or aosp.
the tweak is oriented performance(without sacrifice battery) when screen on and save battery screen off.
the task scheduler is based on IBM recommandation see ici and ici for more info.
with this value the cpu is more available,i obtain good result in vmstat when i launch several app the cpu is less busy.
it improve the task scheduler but not changing score in quadrant same as usual .i obtain 700 that's also a good score for kernel CFS
