Hello Motty,
Okay, so you are using the prefork MPM.
I do not have access to a FreeBSD system.
But the performance issues should be similar to Linux.
You could probably see immediate performance improvements by switching
to worker MPM.
- http://httpd.apache.org/docs/2.2/mod/worker.html
The prefork MPM uses only one thread per process.
So it is more demanding on system resources.
The worker MPM allows for multiple threads per child process.
Here is a quote from the above link:
"By using threads to serve requests, it is able to serve a large number
of requests with fewer system resources than a process-based server.
However, it retains much of the stability of a process-based server by
keeping multiple processes available, each with many threads."
The link also lists several directives that can be tinkered with.
To get the worker MPM you would need to use the --with-mpm=worker option
on the configure step.
- http://httpd.apache.org/docs/2.2/mpm.html#choosing
- http://httpd.apache.org/docs/2.2/install.html#configure
I hope this helps.
Thanks,
Mike

Hello Motty,
You can adjust any number of performance directives as in the
following link:
- http://httpd.apache.org/docs/2.2/mod/mpm_common.html#maxclients
And here is a link for Apache HTTP Server performance tuning in
general:
- http://httpd.apache.org/docs/2.2/misc/perf-tuning.html
What operating system and what MPM are you running?
Thanks,
Mike
