>If even running a "hello" app is too slow, then the whole framework becomes useless Except Yii claims to be fast because it lazily loads extra functionality, such as DB classes and sessions, commonly needed features in most apps. Assuming they use autoload, it would actually suffer a performance hit since autoload is notoriously slow and the other frameworks already have loaded the needed classes.
