I do use output caching, and I know > not everything is actually used in every request. i think youre good to go w/ autoload not loading everything up, but what about existing include / require directives? if the code doesnt already use __autoload() its almost certainly strewn w/ these. so i think if you want the boost from __autoload, not loading up everything, youll at least have to strip these out.
