The results are horrendous for that kind of machine.
Did you tune all your disks ? (see the README of latencytest)
did you turn APM off ? (it caused some spikes on some of my boxes too)
(you can boot the kernel with apm=off on the lilo commandline).
are you using 2.4.5+andrew lowlat patches ?
if yes then in the case you've set the lowlat sysctl option, you need
to set the /proc/..../lowlatency variable to 1 , otherwise it won't work.
let us know if the diagrams get "flatter".
