There is the tuning(7) manual page.
There are better web servers than Apache for demanding loads;
ones that used a non-forking, event-driven I/O model.
Aolserver and thttpd come to mind.
Yaoping Ruan and Vivek Pai from Princeton have reported
excellent results with their "Flash" [1] web server. While
many of their recommended changes to FreeBSD have been folded
into the base source, I'm not sure how many popular web-servers
are using these speedups.
