    I think what we are finding out in the 2.1 kernel is just how bad
    the quality of PeeCee hardware is. I have know that all along,
    but I think the problems in 2.1 are often the hardware's fault.

    A lot of commercial OS offerings are tuned ``slow'' for this reason.
    Its not always because they suck... :)

    The hardware is often incredibly marginal and rarely is a PeeCee
    motherboard within specifications all around. I often marvel that
    Linux or any other OS runs as well as they do.

    Since PCI and PlugNPlay... I have yet to setup a PeeCee where any
    one is not night and day different from another. Setting them up
    is a black art.
