I, for one, think SPEC is great.  We use it a lot in house for
performance tuning.  I get warm fuzzies because I can look at N
different machines as measured by SPEC and the numbers ``make sense''
to me; SPEC seems to do a good job of measuring performance in a
machine independent manner.

On the other hand, SPEC is not the end all to beat all.  No benchmark
is.  If I could design the ideal benchmark, I'd design something that
had a bunch of knobs that I could turn, like an I/O knob, a CPU knob, a
memory knob, etc.  I don't have this, so I run several different
benchmarks that measure these sorts of things.  SPEC is one, Musbus is
another, and we have several internal/proprietary benchmarks as well.
Some people don't like you to quote one figure from one benchmark - I
like to see all the figures from all the benchmarks.  The more data you
have the easier it is to weed out the spikes.
