Why is it that typical FTP data rates are only in the area of
50 kbytes/sec?

I've got an ethernet link between a DN4000 and another machine,
no other hosts on the wire. I figured I'd have to be getting
few to no collisions, and that my throughput would be great.
Wrong.

I'm using thin wire...would I gaining much by going to thick?
Is FTP just a crappy way to move files? Would NFS give me
significantly better throughput? I know about the better
transparency, but how's the performance?

I see variations in data rate (on the comments made by
FTP) from 30 kbytes/sec to 90 kbytes/sec, which seems
kind of flaky to me. Does FTP create its own collisions?

This brings up another point. I've heard lots of salespeople
talking about 100 Mbit/sec Ethernet, and FDDI fiber optic
100 Mbit/sec network support coming up. When can we users
expect actual products?

Thanks to all,
