APC and autoloading

Hi folks, I hope this is the right place for my question ;) Over at the Propel (http://propel.phpdb.org) Dev Mailing List, we're discussing moving to autoloading completely. Someone then mentioned the following ticket: http://pecl.php.net/bugs/bug.php?id=8765 Is it indeed accurate that APC doesn't accelerate _anything_ if a class is loaded via autoloading? I know it doesn't work well with _onces, but PHP 5.2 fixes that from what I understand. I always thought autoloading was the way to go, since it's not doing a _once (for obvious reasons), and it's only loading stuff on demand, so I assumed it to be the fastest of all possible solutions. I'd greatly appreciate any insight on this "issue". Cheers and thanks in advance, David
