Ahem!  The tests we have done involved running 4.1a to 4.1a between
780's over the pronet ring.  We are seeing about 100 kbytes/sec
user-process-to-user-process before the Vaxen burn up. There is
no evidence of any wire-limiting going on.  IP/TCP is a pig
and there ain't no way around it, and the 4.1a TCP is probably
the fastest around. As soon as Sam gets Delta-T
working, I will try it and see what happens.  Should be able
to go a lot faster.  In the near future, we will be connecting
a logic analyzer to the hardware and be taking some detailed
"this many microseconds to do that" kind of measurements.
We do know that because the interface is only single-buffered on the input
side, it can't do back-to-back packets, but that is a small loss
compared to the braindamage of existing Ethernet controllers.

Hope this information, what there is of it, is useful.
