[pypy-dev] Issues with Networkx subgraph function - Slower than cPython

Hello

I have recently tried to move some code across to pypy from cPython, and it takes around 1.5x longer than the cPython implementation (~12 seconds against 19 seconds). Most of the time (90%) is spent in the multiple calls to the subgraph function of networkx. Is there anything that I can do to make pypy faster? I am running the Mac OSX 64 bit binary inside a virtualenv.

Thanks,

Andrew Elliott
