First thing that pops in mind are compiling it with more aggressive
flags and -march=pentium4.
I remembers something about gcc3 bugs regarding SSE/SSE2 but as these
are the CGIs you can allow yourself to at the very least test out what
can you acheive by playing with the compiler args.

That said, the CGIs really need to go, and as codewise nagios 2.0 is
just about ready, it's time to move the web-interface to something else.
My personal suggestion would be in the line of php+smarty.
php-accelerator would be used to increase performance, but not required.
