Message 263946 - Python tracker

I created a repository. I will work there and make some experiment. It would help to have a better idea of the concrete performance. When I will have a better view of all requires changes to get best performances everywhere, I will start a discussion to see which parts are worth it or not. In my latest microbenchmarks, functions calls (C/Python, mixed) are between 8% and 40% faster. I'm now running the CPython benchmark suite.
