Expanding on Jerry and ImOk:
Windows heavily caches DLLs, so DLL loading will be a non-issue.

There are packages out there to cache PHP pages, MMCache was one i read
saw recently. It should be noted that some have problems depending on
os, server, php version, etc, and may lead to instability.

There are also PHP accelerators, which compile PHP source code into PHP
byte code, but again, those have some issues with certain packages and
constructs (iirc, __overload, to name one).
