I'm currently discussing with Maciej Fijalkowski (PyPy) how to get Cython
running on speed.pypy.org (that's what I wrote "cythonrun" for). If it
works out well, we may have it up in a couple of days.
... or maybe not. It may take a little longer due to lack of time on his side.
I would expect that Cython won't be a big winner in this game, given that
it will only compile plain untyped Python code. It's also going to fail
entirely in some of the benchmarks. But I think it's worth having it up
there, simply as a way for us to see where we are performance-wise and to
get quick (nightly) feed-back about optimisations we try. The benchmark
suite is also a nice set of real-world Python code that will allow us to
find compliance issues.
Ok, here's what I have so far. I fixed a couple of bugs in Cython and got
at least some of the benchmarks running. Note that they are actually simple
ones, only a single module. Basically all complex benchmarks fail due to
known bugs, such as Cython def functions not accepting attribute
assignments (e.g. on wrapping). There's also a problem with code that uses
platform specific names conditionally, such as WindowsError when running on
Windows. Cython complains about non-builtin names here. I'm considering to
turn that into a visible warning instead of an error, so that the name
would instead be looked up dynamically to let the code fail at runtime
*iff* it reaches the name lookup.
Anyway, here are the numbers. I got them with "auto_cpdef" enabled,
although that doesn't even seem to make that a big difference. The baseline
is a self-compiled Python 2.7.1+ (about a month old).
