Yii PHP Framework

Also, a reason given for the lack of database handling comparisons is that different frameworks may deal with databases in different ways (some might be really good at creating queries, some might be good at caching, etc). Ok, so turn caching off and most remaining differences should show differences between the frameworks, which is what you want. I could make my own framework and avoid doing a benchmark like Yii's because "some frameworks provide lazy loading, some don't".
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.
I'd be curious to hear about it. Am using CodeIgniter now, but parts of it bug me sometimes.
