    SubjectTerrible VM in 2.4.11+?


    as of the last stable version 2.4.18 VM management does not work for me
    properly. I have Athlon system with 512MB ram, 2.4.18 kernel without any
    additional patches.

    I run following sequence of commands:

    dd if=/dev/zero of=/tmp bs=1M count=512 &
    find / -print &
    { wait a few seconds }

    at this point find stops completely or at least almost stops.

    The same if I copy from /dev/hdf to /dev/hda. XOSVIEW shows only reading or only
    writing (as bdflushd is flushing buffers). It never shows parallel reading and
    writing. /proc/sys/* has default settings. I do not know the reason why i/o
    system stops when bdflushd is flushing buffers nor reading can be done.
