Well these are the numbers on the virtual memory system that I have.
It looks like the SparcStation 2 should make a good xterm server for
15 to 20 people, given my experience with 4/330's.

SparcStation 2 4K 256 64M 64

4/490 8K 1024 256M 32

Thanks to Dean Kemp, Larry Wake and especially to Gordon Irlan for
his article on Sun-4 Virtual Memory Performance. Larry also mentions
that the SparcStation 2 has 16 hardware contexts. I don't have numbers
for the other machines, so I did not put it in the chart.
