kerneloftruth, i got an interesting investigation. if you compile kernel 2.6.36 with ck patches, instead of the zen for bfs, you will get the exact same amount of interactivity in both 2.6.36 and 2.6.37 versions. so, that means the problem isn't in bfs, but apparently some sorta change in zen kernel. ok, so i tried zen kernel with the second patch (most of the patches in the first one are already there) with cfs autogroup and all those cgroup option, and i am pretty impressed with the performance increase. i can again compile with 4 jobs and still play video games and watch hd videos on youtube at the same time.
