It'd still be much slower than C. Perl's performance problems aren't
all due to interpreter startup overhead. And the last time I ran a
server-resident Perl interpreter, it had to be restarted every few
weeks due to memory leaks and memory fragmentation. My servers stay up
for months (if not years) at a time, so I find this unacceptable.

I'd agree with PHP (though it's still nowhere near as fast as C) but
I think JSP would be overkill.

I agree with this point, though if written in C, the fork()/exec()
overhead for such a small program won't be all that bad.
An even better way would be to write it in C as an Apache module.
Anybody here ever program against the Apache module API?
