A comment that sticks out
"Using __autoload and require_once basically destroys any advantage apc
is likely to bring you. Mainly because you move the compilation sequence
into mid-runtime land, where the engine stops execution and proceeds to
compile stuff. "
Although from what I here the require_once issue has been solved with php 5.2

Richard,
Not to doubt your statements, but that seems like the most brain dead design
you could have.
I'm not savvy on the internals of the Zend Engine and OpCode Caches, but why
wouldn't they be able to cache the classes? Seems like a natural thing to
do to me. As for cool and fun, I personally find the idea of autoloading
the better way of doing it. When you start having external dependencies in
your classes, the chain-reaction loading of files can kill you. Especially
when you do not need all the loaded files. Anyway, could you provide some
relevant links about the opcache problems. I've seen lots of people say the
same thing, but never any real proof.
Thanks,
Lee
