I would have thought the CPU itself was comparable to or faster than
a 68040 or 68060 since they was always at much lower clock speeds.

Do you have any local disk or is everything NFS?  If so, that would
be killer for performance.  I remember an old pair of SparcStation 10's
we used to have.  Network builds vs. local disk was already like 5-10x
slower.

How much RAM?
