    Well, laptop P166MMX with 3Com PCMCIA client to my desktop AMD K6-200
    with a cheap ne2k-pci on a RG58 cable copies the binary tarball of my
    test Oracle installation in

    [root@dilbert /mnt]# time cp 805bin.tar.gz /tmp
    0.08user 14.83system 1:54.38elapsed 13%CPU (0avgtext+0avgdata 0maxresident)k
    0inputs+0outputs (80major+10minor)pagefaults 0swaps

    so it means

    [asuardi@dilbert /tmp]$ ls -l 805bin.tar.gz
    -rw-r--r-- 1 root root 73484970 Dec 20 16:50 805bin.tar.gz
    [asuardi@dilbert /tmp]$ bc -ql
    73484970/114.38
    642463.45514950166112956810

    A second attempt finishes in 114.91 seconds. 627KB/s looks nice on a
    cheap home network :) of course there is only me ;)


    Client + server are RH5.2 systems with HJ's knfsd-981204.
