I have a nightly regression build and do a final "ab -k -c6 -t10 .../tenkb.txt"
which is logged. On FreeBSD at least, there has been some ups and downs in
the req/sec on my 266MHz box. The cron job runs at 4am after a full build,
and my (intranet) machine should have little load at that time.

You can see that around Aug 7th, the typical performance went
down from ~350 to ~270 req/s at which it is now performing.
