Let it be noted that the code is kept in _shared_ memory, and IMHO the tradeoff is well worth it. An Apache process that spends longer time processing a PHP-driven request will consume memory for a _longer period of time_ (using an OS that will actually return free()'d memory to the especially during peak times. YMMV of course, but my experience with ZA is that it always increases the performance of your site. That being said, I'm not a big fan of having lots of "trivial" classes wrapping lots of very simple code into a framework of overhead. - Stig
