I highly recommend you get a copy of the DEC Western Research Lab
WRL Research Report 88/4, titled:
 `Measured Capacity of an Ethernet: Myths and Reality'
by Boggs, Mogul, and Kent. It's also in the SIGCOMM '88 proceedings.

They conducted real-world measurements on a test Ethernet, and
found that the wire is capable of sustaining >90% utilization
under most circumstances.

The report is available via email from wrl-techreports@decwrl.de.com in
PostScript form. (Or {...}!decwrl!wrl-techreports for UUCP.)

All you do is send mail to an archive server with the Subject line
containing `send postscript 88/4', and no message in the body.
The file is 602 Kbytes, so the server may take a while to send the
to you, but you will get an acknowledgement of your request.

You can also say `send help' to get a more informative message, see
how to get an index to all the reports, etc.
