Acknowledging in advance that the answer in large part depends on
the applications being run (which I'm NOT telling you, just to make this 
more of a challenge...):
At what point does adding memory to a Sun3/75 reach the point of
sharply diminishing returns?  We have fast disks on our file servers
(Eagles), and four meg on our 3/75's.  It seems pretty clear that swapping
is sharply reduced in going from two meg to four; is there much gained
by going to eight, or even sixteen?  What about servers?  Is there
much to be gained by beefing up server memory to eight or sixteen meg?

Thanks in advance,
Chuck Howell
