I just did a benchmark with 2 MacIIs, one Ethernetted and one
LocalTalked, transfering a 470k system file. I used the MPW
'duplicate' command. Results:

    LocalTalk (through a bridge) - 138kbit/s
    EtherTalk (same wire)	 - 418kbit/s

Doesn't look like 20% to me. For that matter, if the LocalTalk
transfer ran at full speed (c. 95% of 230kbit/s) it would still be
about an 80% speedup.

Based on our group's experience, I would say that the main advantage
of EtherTalk (besides fast FTPs to UNIX machines) is that you can use
a file server as conveniently as your own disk, and so can 20 other
people.
