   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?
