Most of our machines do 800-1000 kbps on an isolated ethernet. Ofcourse
if you do this test by FTP you'll have to do it twice in a row; the first time
you're also measuring the disk I/O speed of the server.
Actually you should do a "get bigfile /dev/null" twice to get a real good
idea of the performance.
Even an old ISA WD8013 can do 800-900 kbps under Linux..
