Perhaps you can describe some of the bottlenecks you're experiencing,
or post some code fragments?  The lsprof profiler has worked for me:

Psyco for the most part does not work on non-Intel processors.  PyPy
static translation does work if you write in RPython, but debugging
translation failures is time-consuming and not particularly easy.

If you have any free x86 boxes, you might do what I do - write on the
Mac and run somewhere else faster, perhaps with Psyco.  That also has
the benefit of keeping your Mac free for interactive use.
