[pypy-dev] Is PyPy appropriate for Django?

[Andy]

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.
