I'm trying to get some clearer idea of what kind of performance to expect
using a VAXserver-3500 to serve a group (12-15) DECStation-2100's (each
with 8M) in a graphics/CAD sort of environment. Note that it is an educational
sort of setting, so it isn't quite the same as having 12-15 CAD engineers
banging away 8hr a day. But what I'd like to get some idea of is:

1) is it totally ridiculous?

2) is it going to be only marginally painful, somewhat ok, etc?


I don't have much experience with Ultrix workstations, only with VMS
and LAVC based stuff. Any insight folks could give me would be good.

Also, the configuration of the 3500 is as follows:

16M memory
DELQA ethernet
KDA50 disk controller
RA70 
2 SI83C (these are fujitsu drives, hacked up to act like RA82's. 16ms access 
time though)

The net these things would be on is unloaded (ie, just these machines and a 
couple of standalone systems, which generate virtually no traffic).

We would be adding a SCSI controller + a few CDC Wren V's to the 3500 to boost
the available disk space (for a total of around 2.5Gig).

Also, how much bigger are the binaries for Risc/Ultrix machines?

thanks alot.
