I don't think there was a single place where I said PHP was faster than
C, nor did I imply it.

The point I was making is simple, if you have a shitty algorithm (which
is the case for our op) expect shitty performance.

There's no doubt you will gain performance moving to C, but, if properly
designed, you have a performance that is acceptable, then why go to that
level?
