While I'm not a pypy developer, I know they treat any python* code running slower than cpython as a bug. They love to try and help with it if you stop by #pypy on freenode irc.
It's best if you can give them a self contained example they can download and run themselves to track down what is going on. If not (because it is closed source or such) they may or may not be able to do much, but are still more than happy to try and give some advice at least.

* pure python, certain methods of interfacing with extension modules will probably always be rather slow and the solution is generally to either get rid of it or rewrite the interface to it using cffi.
