Many moons ago I came across a script that I could run on my apache2 server and it would calculate a pretty good estimate of what settings I should have for my mpm-worker/mpm_prefork module settings in my apache2.conf file. I have since lost it and don't even remember what it was called. Anybody know of one similar?
I don't know such a script, but this link might be useful: http://www.howtoforge.com/configuring_apache_for_maximum_performance
