[Python-Dev] Benchmarking Python and micro-optimizations

[Victor Stinner]

Hi,

I removed all old benchmarks results and I started to run manually
benchmarks. The timeline view is interesting to investigate
performance regression:
https://speed.python.org/timeline/#/?exe=3&ben=grid&env=1&revs=50&equid=off&quarts=on&extr=on

For example, it seems like call_method became slower between Oct 9 and
Oct 20: 35.9 ms => 59.9 ms:
https://speed.python.org/timeline/#/?exe=3&ben=call_method&env=1&revs=50&equid=off&quarts=on&extr=on

I don't know well the hardware of the benchmark runner, so maybe it's
an issue with the server running benchmarks?
