How do I speed it up? That's a tough one, in general. There are many tricks to speed up Python code; consider rewriting parts in C as a last resort. -In some cases it's possible to automatically translate Python to C or x86 -assembly language, meaning that you don't have to modify your code to gain -increased speed. - -.. XXX seems to have overlap with other questions! - `Cython <http://cython.org>`_ and `Pyrex <http://www.cosc.canterbury.ac.nz/~greg/python/Pyrex/>`_ can compile a slightly modified version of Python code into a C extension, and -can be used on many different platforms. - -`Psyco <http://psyco.sourceforge.net>`_ is a just-in-time compiler that -translates Python code into x86 assembly language. If you can use it, Psyco can -provide dramatic speedups for critical functions. +can be used on many different platforms. Depending on your code, Cython +may be able to make it significantly faster than when run by the Python +interpreter. The rest of this answer will discuss various tricks for squeezing a bit more speed out of Python code. *Never* apply any optimization tricks unless you know |
