Here at the MIT AI Lab we have found that our diskless sun workstations
put a much heavier load on an Ethernet than Hedrick and Johnson noted.
Using a network analyzier, the 18 diskless Suns we have on one ether
can run the cable at 50 percent of capacity for extended periods of
time. Peek 5 second usage often jumps to 70 percent. All our machines
have 8 Meg of RAM, though some of them run Sun Common Lisp. Much of
the traffic is ND packets. Based on this, we are planning on having no
more than 12-15 Suns are one ethernet. Each server will have its own
"client" subnet.
