Profilers
---------
profile.py affects the runtime but pretty accurate

hotshot was introduced in 2.1 or 2.2 has lower runtime overhead

Boa constrictor ("Delphi for Python") also has a profiler

Misc
----
Thread locks in Python can cause performance problems

Pyrex is python compatible

Boost::Python works well on PC

Someone ported to GameCube, squeezed out float, long int, file support, modules, etc. got down to 340k

Look up Python on embedded systems article

Python for 8-bit microcontrollers is coming: many limitations but 63k and no heap usage

__slots__ space efficient statically sized objects

Python normally 1.7 MB footprint

Lua has a 100k footprint including compiler and interpreter and is much faster.  Has patches for reference counting instead of mark and sweep garbage collection.  Easy to timeslice.

www.python.org good for support, see python-dev mailing list.
