We are in the same situation here, it's hard to ingore the spec numbers
even if when you don't trust them. I don't have any woodcrest machines
yet but early reports from other people tell us that for *our* workloads
the woodcrest performance isn't as good as the spec numbers lead you to
believe and you see some performance loss (because of the FSB I guess)
when you run multiple jobs. It *is* faster than the Opteron though for our
workload.
