Creon Levitt and Eugene Myia at NASA-AMES did a fairly complete set of
tests on the Hyperchannel;  they will probably send you a copy of it
if you like.

Locally, between a 780 and a 750, we see data rates on the order
of 80 Kbytes/sec of user->user data, which is similar to our other
interfaces (ethernet, etc).

Of course, for us the choice of Hyperchannel for that particular room
was necessitated by having to talk to a Cyber 750 running NOS2.
The fact that the VAXen can talk amongst themselves over the Hyperchannel
is incidental.

If you are looking for something REALLY FAST to interconnect just
minis and super-minis, try the 80 Mbit PRONET;  much cheaper than
Hyperchannel.

	Best,
