Every piece of data I've seen contradicts Bob's claim.  As a wild guess, I might
say he saw multi-CPU numbers that either got reported as single-CPU, or someone
just assumed they were single-CPU numbers.  However, I haven't actually seen the
numbers Bob saw - there is some chance that what he reported is accurate.

As you pointed out near the very end, the Intel/HP people who submitted the SPEC
scores didn't do much better.  I would hope that they _are_ professional
performance engineers.

From what I understand, profiling is quite important for Itanium to get good
results.  This is why even the base SPEC scores were achieved with profiling
runs, AFAIK.
