I'm still not convinced by the use of nothing but 'Hello, world' for the performance comparisons. Sure there may be some cases where you only need similar functionality, but since Yii's advantage comes from lazy loading features like DB libraries, what happens when those libraries are actually used? In real-world scenarios, those performance improvements may be nullified.<p>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, <i>which is what you want</i>. I could make my own framework and avoid doing a benchmark like Yii's because "some frameworks provide lazy loading, some don't".
