Seconded. I recently took some distance computation code and  
Cythonized it, I got an absolutely absurd speedup after about five  
minutes of effort to remind myself how numpy+cython play together  
(see: http://wiki.cython.org/tutorials/numpy ).

I know some people are reluctant to use anything where their code  
isn't standard python (possibly with ctypes fiddling) but Cython is  
definitely worth it for replacing bottlenecks.
