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?
I think most people just want you to use the exact same configuration
file on both systems and verify that both use the same pre-compiled
options as well. Probably the best thing to do is build from source
on both linux and freebsd with the same options. Make sure the
defaults for each system are fair as well. Then use the same config
file or as close as possible on both operating systems. Otherwise,
you're not testing the same thing. If you were testing against
another architecture like say windows, then you would need to use the
default worker type for windows.
