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.
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".
I think bootstrap time is an important comparison since it gives a hard boundary on how fast the framework can operate. If even running a "hello" app is too slow, then the whole framework becomes useless, no matter how much you streamline and cache your application.

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 run www.trackmycv.com and www.finddjs.co.uk on it as well as several company intranets. I've been using it for about 18 months, in my opinion it's the quickest, cleanest PHP framework out there. It's got loads of features, it's well documented, sanely laid out and fully extendible, can't recommend it highly enough
