If you need more speed, `Psyco <http://psyco.sourceforge.net/>`_ generates x86
assembly code from Python bytecode. You can use Psyco to compile the most
time-critical functions in your code, and gain a significant improvement with
very little effort, as long as you're running on a machine with an
x86-compatible processor.
