 There were a few problems with the last set of tests. First off, the
headers that the scripts had been returning were dodgy, so it was aborting
the connection. Also, I'd left ldap defined for host & name lookups in
/etc/nsswitch.conf. And LDAP servers get stressed when you hit them a lot,
and refuse to talk to you :)

 So here they are again, and should be considered a lot more accurate.

    cgi-bin Perl:  122 seconds   81 hits/sec (load 20)
    mod perl    :   34 seconds  294 hits/sec (load 18)
    PHP         :  270 seconds   36 hits/sec (load 28)
    AolServer   :   14          686 hits/sec (load  8)

 AolServer has a builtin tcl interpreter to do the job of modperl. The
results sorta speak for themselves. I'm not sure what's up with PHP. I'm
using just a small embedded PHP script, and not an external interpreter.
Whatever it's doing, it's killing it.

 Either way, AOLserver rocks.
