    I've checked the same file on *different* server, but it has very similar
    hardware (not Dell, but also Dual Xeon 2.8, SCSI, 2GB ram, etc...).
    It was on FreeBSD 4.10.

    # time tar -xf mysql-m.tgz
    0.244u 33.724s 4:25.26 12.8% 374+291k 14216+1828io 8pf+0w

    During this test server was loaded (load averange about 1.00, Apache, MySQL
    running). I wasn't able to turn deamons off but I suspect this result
    could be much better than it was.

    So is my problem only FreeBSD5 releated? Seems to be.
