Next, can you re-run your tests with a more recent version of ZF? We made some changes to Zend_Loader to optimize it slightly -- primarily, we removed the call to isReadable() prior to loading a class file; this removes one stat call, which makes a pretty significant difference in Zend_Loader's performance as an autoloader. Our internal tests show that at this point, Zend_Loader tends to perform within a few percentage points of a straight require_once. Third, would it be possible for you to publish the code you used to test, as well as the specs of the environments you tested in (OS, PHP version, php.ini settings, ZF version, etc.)? It's hard to take these numbers credibly when nobody can independently verify them. Thanks!
