It is nicksched vs mainline. Note: this is not realtime scheduling latency, but latency as measured by my random program. It also does not indicate interactivity, because the latencies measured were all under 15ms which is probably below perception. Even if not, it doesn't measure latency as you might see it. Finally, some of the tests involved me moving the mouse around, so factor in by subliminal (or not) bias toward my scheduler. http://www.kerneltrap.org/~npiggin/schedlat3/index.html
