Its speed is nothing mind blowing to me, the hello world take around 2ms with xdebug and my own framework take about that long. I have not used its model and while it may look fast, it provide no functionality for retrieving/saving data and the only functionality i see is validation and error checking(not sure the difference).
This really seems like nothing special or anything. The model portion may be faster but does nothing special and has very limited functionality to save coding time. My framework too could say that it is nothing special as i am not adding a ton of new things that no other MVC and/or ORM framework has however my goal has been cleaner and faster code as from earlier testing, my framework(with a custom ORM system) is 2 times faster for loading the same amount of data from a model than the doctrine ORM(and Doctrine does not even do MVC stuff like parse url, load controller, load view.
