If you don't know yet, you could find interesting this project:


They too are trying to improve CPython speed.

If you are thinking of language variations  that trade some flexiblity 
for speed, you might be interested in Cython:


As a simple and plain python user, I would value a version of cython that 
can be used to built faster executables out of almost-python code (that 
is python code with a few additional restructions). Maybe using typing 
inference to avoid declaring explicitely the variable types.

Another interesting place to go is pypy : http://codespeak.net/pypy/dist/
pypy/doc/ . They too have developed a restriced version of python 
(RPython, I think) which should be faster than CPython. They don't work 
with CPython code base, but could give you ideas on what are the 
bottlenecks of python as a language.
