If you're trying to measure measure network performance, why don't you use a tool which is suitable for the job? FTP is definitely not a good tool for this job. I'd suggest ttcp or NetPerf. Btw, I've measured more than a megabyte/s myself with NE2000 clones (Kingston) on a 486, using ttcp. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
