Wesleyan is replacing a DECSYSTEM-20 with another machine which may end up
being a VAX 8550 or 8700.  If so, we're planning to have access to the machine
be 100% through Ethernet via TCP/IP terminal servers.

We're running the CMU version of Tektronix TCP/IP.  Now, the questions:

1) Does anyone have any experience running 100 or so concurrent users over
   a TCP/IP network to a VAX?  (Via any software, not just Tektronix.)

2) Can anyone guess at the performance penalty we'd pay, compared with using
   straight serial connections via DMF-32s or something?

I know that LAT terminal servers would work much more efficiently, but we
have other non-DEC mainframes which are only accessable through TCP/IP.

Thanks for any opinions or advice you can offer.
