apache2 tuning

[Thomas Krause (Webmatic)]

Hello,

I want to build a new webserver (dual xeon with 4 GB RAM).
The server provides mostly dynamic php-pages. In the
ports Makefile there are compile option like WITH_THREADS
and WITH_MPM (which includes WITH_THREADS). These are
useful options for a production machine? Also, is it
useful to compile the kernel with ACCEPT_FILTER_DATA and
ACCEPT_FILTER_HTTP? And if yes, is apache compiled with
accept filter by default?

Kind regards,
Thomas.
