my [kernel scheduler] Load balancing tick is very high about 1000. I have installed E17 and gnome 2.30.2 in gentoo . Now I am in gnome when I run the powertop . My kernel is gentoo-sources 2.6.35-r13. Before when my kernel is gentoo-sources 2.6.34-r12 , the number is also high . How to decrease the number ?
Thanks a lot !
