PyPy looks pretty sweet.  I'm glad this discussion was started.  There
always seems to be this buzz about python being slow.  So what if it's
not as fast as C?  I make that up by cutting down development time.  I
figured if I ever ran into something being too slow, that I'd just
have to learn c extensions and replace the bottle necks.  In 2007 I
wrote a system in python that communicated to an autopilot on an
autonomously flying aircraft at real-time.  We never had any speed
issues.  I have not played with django much and I do not typically
develop web apps, but the slowness really must be bloated algorithms
in the libraries you are using.  Programming in other languages (java,
c, c++, c# etc) is not an issue for me, but next to python it's like
writing with a feather and ink instead of a ball point pen.  I have to
put more time into working with the tools I'm using than actually
getting the job done.
