    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.
