PHP Opcode Cache Links

Here’s a few links talking about the PHP opcode cache, which came out of a discussion on the Zend Framework mailing list about whether or not Zend Framework benefits from APC and other Opcode Caches.

The general gist of things is if you have a hierarchy of functions like Zend Framework does and code in a one-class-per-file style and include conditionally (based upon autoload and other mechanisms like includes inside conditionals), then you may take a corresponding performance hit. However: This should be fixed in PHP 5.3.
