# Something doesn't compute here.  For most things, a 32016/10Mhz box is

If you ask it to calculate floating point stuff, it's about equal to a 750
without an FP750 (i.e., 750 running floating point emulation).  If you ask it
to sort integers, it's about 70% of a 750.  If you ask it to do lots of
procedure calls, it's about 70% of a 750.  If you run a tight loop doing
arithmetic on some registers, it's about 70% or 80%.

If you put two users on both machines, running VI or JOVE, it's about half a
750.  If you put four users on them, it's about 10% of a 750 on a per-user
basis.

Half a 750 seems about right to me after using both for extended periods of
time.
