Four-way 100MHz boxes? I don't recall Sun making something like
that. What kinds of machines were they exactly?
FWIW, it appears that the UltraSPARC II is slightly less efficient
(by maybe 20%) per-clock than the G3, but that's not a bad deal
overall - the G3 is known to be exceptionally good in that area.
Keep in mind that your E450 is an SMP box, but the code you're
running almost certainly is not parallelized. So, you're only going
to be using one CPU.
It would be interesting to compare these hashcash benchmarks
against the SPEC CPU benchmarks at <http://www.spec.org/cpu2000/>, as
well as the predecessors, so that we can try to get some sort of idea
how various classes of machines will perform.
If you can point me at the code, I can run the same test on a
variety of hardware I have access to, which may provide some useful
additional data points.
