The 2.4-ac tree has the O(1) scheduler as has stuff like Red Hat. From my own poking around the main reason people see lack of snappy performance is twofold - Using unaccelerated X setups - The lack of render acceleration At startup there are some problems with toolkits and with X protocol issues (Jim Gettys did a great talk on this) and a chunk of similar things with loading binaries, disk head algorithms and similar kernel areas. Once apps are running the big one is the lack of support in X drivers for "dma block from screen to ram" or "dma block from screen to agp space" both of which would make unaccelerated render way way faster
