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.
