Yes, sorry if I was unclear. It's

Just to clarify, from what I understood, they basically ran
timeit.repeat(stmt, repeat=
Thanks to Armin and Maciej.
I will try to build a OpenCV-PyPy prototype with cffi first.

I'm curious whether I'm the only one to find this paper disappointing?
To summarize, the authors developed a translation system into C++ for a
very restricted subs

I don't know OpenCV myself, but writing a CFFI module accessing it
should be easy, even if there are functions that take numpy arrays.
You can do:

Hi Amaury,
In fd331e4bf733 you did an untested change to the tkinter library; as
it turns out, the CPython tests find problems:

Can you fix the situation? Th
Hi Boxiang.
You're far better off doing it with cffi and writing part of it in C
(pure C) or Python. Cffi on pypy is quite well optimized and should
not really present a performance overhead.

I think some of our poor performance is because they never let the
jit warm up, but should we grab some of their benchmarks and
see if we can do better?
