Here is an initial version of a micro-benchmark for C function calling: https://github.com/jdemeyer/callbench I don't have results yet, since I'm struggling to find the right options to "perf timeit" to get a stable result. If somebody knows how to do this, help is welcome.

I suggest --duplicate 10 option.

While it is good for start point, please don't forget we need "application" benchmark.

Even if some function call overhead can be 3x faster, if it takes only 3% of application execution time, total execution time only 1% faster. It's too small to accept PEP 580 complexity.

Realistic application benchmark demonstrates not only "how much faster", but also "how important it is".
