Provably faster?
I can't find support for that on http://pypy.org
http://speed.pypy.org/
The charts on that page refuse to display in IE.
Nevertheless, it doesn't seem to compare against C, but against CPython.
Not exactly rigorous mathematical proof, but pretty strong evidence. Also, I use
PyPy once in a while for projects where speed matters a little but I want to
share my code with Python people or want to use Python's huge standard library.
Anecdotally, it's definitely faster. The reason has nothing to do with the
language it's written in. It's because PyPy JIT compiles a lot of the Python
code instead of interpreting it.
