For CPython, the resulting bytecode consist of instructions for a virtual  
machine, like Java.
I believe Jython compiles Python code into Java bytecode and executes  
using the Java VM.

If you only care about speed, maybe Python isn't the right tool to use in  
the first place.

There are some performance tips here:  
<http://wiki.python.org/moin/PythonSpeed/PerformanceTips> and you can use  
tools like Psyco, Pyrex and ShedSkin to improve performance dramatically.
