Ok, did anybody read my initial post?
I'm NOT setting up a production machine. I'm NOT using PHP - it was
mentioned as a reason threaded apache is not widely used. I've run "ab
-n 100000 -c 100 http://localhost/" where "http://localhost/" references
a small static HTML file, served by apache 2.0.x. PHP was not even
included in both apache setups. I've run this on a 8-cpu Xeon beast (ok,
not really - 4 cpus, tried with hyperthreading on and off) and got
terrible performance. This performance is objectively low even by
itself, without any comparison with other operating systems (such as linux).
What I *am* doing now is looking for someone who has a 4 CPU or bigger
machine idle on which he/she can replicate this simple benchmark (it
really IS simple - you need apache20 port in default configuration -
everything's included) and confirm or contradict my results. I won't
tell exactly what my results are because: a) to encourage fairness and
b) because they are so ridiculously low that if I'm wrong I don't want
it to end up in mailing list archives for posterity :)

This has nothing to do with my original intent but I must reply. Under
the context of my "benchmark", you're practically saying that doing this
on Linux (and no, +/- 10 servers ready doesn't make a difference when
there are 100 simultaneous connections involved) is ok, but on FreeBSD
it isn't because of...what? Lack of objectivity?
