PHP Frameworks (CodeIgniter, Yii, CakePHP) vs. Django
I am using CodeIgniter 1.7.2 and for complex websites it's very good and powerfull, but it definitely is missing some kind of code generator which will allow for example to build an IT application in one click.
I had the impression (from watching a tutorial) that Django has it.
I have to develop a site which has to accomodate around 2000 users a day and speed is a criterion for it. Moreover, the site is a user oriented one where the user will be able to log in and check his profile, register for specific events he/she wants to participate in. The site is to be hosted on a VPS server.Although I have pretty good experience with python and PHP but I have no idea how to use either of the framework. We have plenty of time to experiment and learn one of the above frameworks.Could you please specify which one would be preferred for such a scenario considering speed, features, and security of the site. 
Thanks,
niting
