    The default on my RH system with the latest errata kernel is as follows:

    [root@sevilla kmaraas]# elvtune /dev/hda

    /dev/hda elevator ID 0
    read_latency: 8192
    write_latency: 16384
    max_bomb_segments: 6

    [root@sevilla kmaraas]# uname -a
    Linux 2.4.18-17.7.x #1 Tue Oct 8 13:33:14 EDT 2002 i686
    [root@sevilla kmaraas]#

    Is this worth changing to lower values then? They seem to be an awful
    lot higher than the values mentioned below here.
