From what I've been able to read, web.py is supposed to be much faster than PHP. Is this true? What are the reasons that web.py hasn't made it main stream yet and why is everyone using Django rather than web.py?

I know Django is more pythonic, but web.py, to me, seems more PHP-ish.

I made posts before about approaches similar to PHP and I'm surprised that web.py wasn't mentioned. It seems like there isn't much of a web.py userbase. Is there a reason?
