    SubjectRe: Linux 2.4.17 vs 2.2.19 vs rml new VM
    Just .02 from the peanut gallery -

    It would be interesting if you were to compare and
    contrast 2.4.17-preempt with 2.4.17-low-latency.

    I find the low latency patch makes a noticeable
    difference in e.g. q3a and rtcw - OTOH I have
    not been able to discern any tangible difference
    from the stock kernel when using -preempt.
