    Hi!

    I am not a hacker but I read linux-kernel with great interest.
    (maybe when I grow up I become a kernel-hacker ;-) )

    Yes! Interactive feel is more important for me than any benchmark result.
    As I always let play x11amp my favorite music in the background, it's also
    important that there are no breaks in the playback. So I booted my P166MMX
    with 128MB of RAM (SCSI-only) with mem=16M (your pre7-patch applied).

    Here my subjective comment:

    I am running X (fvwm2), netscape, 'find /' in an xterm, x11amp,
    kicq and writing this email with Pine.

    There are no problems except the cursor jumps around when I am moving my
    mouse (I run X with a priority of -18, a good idea?).

    X11amp (suid root, the readme says that it'll run in 'realtime-mode'
    then) randomly stops playing for a few milliseconds (while swapping).

    Starting another xterm takes about 6 seconds. Console-switching is fast.
    No need to say that netscape reacts really slowly.

    Network throughput is normal I think (~620 K/sec on a 10Mbit LAN, NE2000
    compatible PCI-network card).

    Attached is a ps snapshot of running processes.

    Btw with 128MB RAM it's hardly possible to make x11amp pausing playback.

    'free' says:

    total used free shared buffers cached
    Mem: 14576 14192 384 6628 348 6724
    -/+ buffers/cache: 7120 7456
    Swap: 66460 23572 42888

    I am very happy with current linux-kernels. No hang, no oops, no reboot,
    no problems (and never had). Really good work!

    Greetings,
    Stefan
