Poorly stated, what I meant was not "mitigated" but "addressed".  In
some cases the raw benchmarks may not tell the whole story, such as
the tradeoff for audit that Adam mentions, but...

...regardless, the same results happen with our packaged httpd means
we should at least try to identify the culprit.  Mainly, I would like
in general to see more context around benchmarking before it's touted
as authoritative.  I'm speaking from the general perspective of
someone not enamored of sound-bite news.
