I've seen numerous references that calling require_once is slow. Zend Framework is very strict about not calling require_once unless absolutely necessary (e.g. for exceptions).
In item 3 in this blog post: http://till.vox.com/library/post/zendframework-performance.html the author claims switching to __autoload chopped 220 ms off request times. Why is this so? If you do not call require_once until you actually need the class, I fail to see why __autoload would make any difference as you still need to read the file from disk and interpret it either way.
