    Ehhhm, ATM is slow ;-).

    Linux talks quite happily on HIPPI[1] networks, in fact with a dual P2
    400MHz 440BX box I am able to compete with Sun, DEC and SGI (the
    performance I've seen in AIX is a lot lower). Basically I have seen
    the box do 75MB/sec on receive with single stream TCP, and IP
    checksums computed by the kernel (a 440LX dual 300MHz does 50-60MB/sec
    or something like that). Better memory bandwidth and I believe I can
    go even higher.

    [1]: HIPPI is an 800Mbit/sec switched network, for those who are
    interested in more info about HIPPI and Linux/HIPPI, you might want to
    take a look at my LinuxExpo paper from earlier this year, at
    http://wwwcn.cern.ch/~jes/hippi/hippi-paper.ps - please notice the
    performance figures are severely outdated ;-)
