I'm using the new scheduler since a few days and I have to say that this is an amazing improvement for gaming loads. When playing enemy-territory the animations are completly smooth and fluid, without any hiccups. Et runs now clearly better on Linux than on my Win XP partition (same HW). I have never seen such smooth animations on any OS before. (I have LD_PRELOADED a libnoyield ripped from a post here on lkml) I can play et and have a 'nice make -j4' in the background and the only thing you notice is longer load-times/more latency on disk access. I can't tell if the compilation is finished or not while gaming ;-) On everyday dektop usage there is a slight improvement too. But for me the current mainline scheduler has no problems. I couldn't tell which scheduler is in use by only doing desktop related things. Mainline scheduler is good and has no probs there. I didn't find any severe regressions on my dual core system. No problems with sound or video even with make -j8 kernel compile in the background. When I start a single cpu-hog it tends to jump around cores every second or so. I think that this is a regression to the current scheduler which tends to have a better affinity management on multicore. Really nice work Con! ;-) -Christian
