(Multiprocessing also helped, and I was using that too.)

That being said, it would appear from my initial reading that 1) Psyco is considered obsolete and is no longer maintained, 2) Psyco is being superseded by PyPy, 3) PyPy doesn't support Python 3.x, or 64-bit optimizations.

Pypy is working on porting to python 3. They are accepting donations:
