Some ideas:

  • Reimplement uri module functions in C (in whole or in part)
  • implementing a string buffer class (and make available as a separate project) to use where string concatenation is currently used
  • Routing logic (tree-based lookup in C)

I did some exploratory testing of cffi and the thunking/marshaling is fairly expensive compared to actually running the C code. It may be better to use the Cython programming language (optionally) for certain hot code paths, but leave them as regular python when running under pypy...
