As several other people have pointed out, there is a mild overhead to OO PHP, but you can offset it by focusing your optimization effort on the core classes that your various other classes derive from. This is why C++ is becoming increasingly popular in the world of high-performance computing, traditionally the realm of C and Fortran.

Personally, I've never seen a PHP server that was CPU-constrained. Check your RAM use (you can optimize the core classes for this as well) and make sure you're not making unnecessary database calls, which are orders of magnitude more expensive than any extra CPU work you're doing.
