    Subjectscheduler improvements : 2.6.21 vs 2.6.22-ck1 vs 2.6.23-rc6

    Warning: I have not run any benchmarks. One thing I am (more or less)
    able to measure is my own ability to headshot in some games like UT99.
    The other thing is to see if flash videos stutter or die under load.
    Please remember, this is about desktop usage - not numbers.

    my computer:
    PIII-S 1400 (512KB L2)
    TUSL2-C (i815ep)
    512MB PC133
    FireGL 8800 (~Radeon 8500 128MB) with dri drivers

    Hello Ingo, LKML,

    Here are the results of a few informal tests (flash videos, playing
    UT99, and looping kernel compilation in background).

    * is OK but interactivity is not good (i.e. I sometimes
    get "lag" under load).

    * 2.6.22-ck1 is better, interactivity-wise, but becomes unusable under
    load (i.e. a kernel compilation + desktop switch breaks flash
    videos ; UT99 is too slow when compiling too).

    * 2.6.23-rc6 is... perfect, as good as can be on my old PC. Flash never
    breaks even on high I/O or compilation load (within reasonable
    limits). Gaming is great, which wasn't the case before.

    Thanks for the good work.
