Did you find the bottleneck?

- Notes on MPM's: Currently, you can expect good performance with
prefork and worker. perchild is b0rked and threadpool is
- Using apache2 with PHP is *safe* with prefork.
- worker MPM use KSE and performs well, with a custom apache2 (see
options for apache2 port), in some cases, worker MPM outperforms
- If you use apache2 in ports tree, you can try apr_poll() patch which
supports kqueue, define WITH_EXPERIMENTAL_PATCHES.
It's pretty stable and improves significantly apache reponsivness.
