Especially in mozilla-firefox ... Using 2.6.22 or 2.6.22-cfs19 my firefox hangs for some time(~4-5 seconds) when I'm trying to open any url, but with 2.6.22-ck1 firefox doesn't hang at all or at least for a second when I have lots of open tabs. What is the reason? Had Con made better scheduler than cfs and O(1) in general kernel? Kernel configuration in 2.6.22, 2.6.22-ck1, 2.6.22-cfs19 is similar.
