what is the best way to profile code written in pyrex?

Cython has Python profiling support. You can compile a module with profiling enabled, and it will trace function calls into cProfile, even calls to cdef functions.

http://docs.cython.org/src/tutorial/profiling_tutorial.html

If you need more low-level profiling data, use valgrind's callgrind. It has a great visualisation tool available that is called kcachegrind.
