Do similar results occur when you compare the installed Apaches instead,
or does the discrepancy go away?

Why would you want to mitigate that, in a comparison of distributions
out-of-the-box?  (And, what would "mitigate" mean here?)

I guess I feel pretty consequentialist about this -- if the discrepancy
they measured doesn't actually exist in a form that our users might
hit, then they were wrong to post a badly-designed benchmark.

If it does exist, on the other hand, they've done us a large favour
by pointing out something we didn't know about (which might even be a
large regression from F10), and I'd feel that we should (a) thank them
and encourage them to run benchmarks more often, (b) fix our bug, and
(c) tell them how to improve their benchmarks, with patches, so that
it doesn't take so long to work out whether there's a real problem
next time.

The question is, which is it?
