Hi Andy
I'm using our own internal platform which uses CherryPy, sqlalchemy and Routes. Currently I get a 20% \
speedup once JIT has completed; most of this I think has to do with our own native code that's not very \
friendly to PyPy JIT (lots of generators and **kwargs passing), so I'm hoping to get that better. I \
haven't monitored memory usage specifically
Cheers
David

Hi David,
Which platform are you using?
How big of a speedup did you get? Did the memory footprint increased significantly?
Thanks.

I'm not using Django but another web platform; I've found some speedup using pypy after the JIT has \
kicked in, but it did require some profiling and adjusting of my code. Why not give pypy a go?

Hi,
In the PyPy benchmark there's a Django test that shows tremendous speedup of Django when running \
PyPy-JIT. But that is just for Django templates. What about the other parts of Django?
1) For URL routing Django uses the re module, which is a C extension. Would JIT work with that?
2) Other parts such as DB driver also contains C code, again would that work with JIT? I suppose I could \
use a pure Python driver, but would a JIT'd pure Python driver be much slower than a native driver?
In general are there any rules of thumbs regarding PyPy and C extensions - what works, what doesn't?
Thanks.
