Tuning: not yet, all scheduler parameters were default Result: base 2.6.21 showed some pauses and after the pause the sound got louder for a short time (<500ms). With sd-0.46 the playback had many glitches and finally just stopped with the display looping on a small number of frames and no sound. The skips were repeatable, the hang was only two of five runs, I didn't let them go until the make finished (todo list) but killed the mplayer after 10-15 sec. No glitches observed with cfsv7, I thought I saw one but repeating with granularity set to 500000 and then with no make running convinced me that it's just a crappy piece of animation at that point. I ran glxgears, again sd-0.46 had frequent pauses and uneven fps reported. Stock 2.6.21 had a visible pause when the frame rate was output, otherwise minimal pauses. CFSv7 appeared smooth at about 250 fps. All tests gave acceptable typing echo, it seems that X is getting enough time at that load to echo without major issues. I will be doing tests with server load later this week, have to add disk for the database. Hope this initial report is useful, I may be able to update ctxbench later today and try that. -- Bill Davidsen "We have more to fear from the bungling of the incompetent than from the machinations of the wicked." - from Slashdot
