RPython can be faster than C
(yes, C as in language, not c as in speed of light). I looked recently at the great computer language shootout, for some benchmarks and to make some speed comparisons. I use this benchmark, modified it to be rpythonic-enough and compared speeds. The code is here (the only change from the Python version was to create a class instead of tuple, so actually this version is more OO). Also the benchmark

PyPy - The RPython Toolchain — PyPy v1.5 documentation
This document describes the toolchain that we have developed to analyze and “compile†RPython programs (like PyPy itself) to various target platforms. It consists of three broad sections: a slightly simplified overview, a brief introduction to each of the major components of our toolchain and then a more comprehensive section describing how the pieces fit together.
