I don't know about needing 8 CPUs - we run just about the same amount of
disk with 6 and so far disk is simply not an issue (This is on a Sequent
S81).  It wouldn't seem that it is all that likely all your users will
be using wildly different disk areas at the same times, but if they were
then that would possibly make a difference.

On the other hand, we run 48Mb of memory.  Since a lot of memory is used
in caching, I imagine that makes a large impact.

I will say, though, that on occasion I've been able to tell that having
the extra processors seems to make a large difference - several jobs have
been running using very high proportions of a couple of the CPUs and the
fact we had other CPUs available pretty well 'hid' this from the rest
of the users.


For what its worth...
