The nice thing with benchmarks is that you can always take a subset of numbers to prove something :-) Another subset where Python 3.6 is faster: "Python 3.6 is between 12% (1.14x) and 97% (32x) FASTER than Python 2.7 in the following benchmarks:" https://twitter.com/VictorStinner/status/7945252896

(Re-post without the two attached files of 100 KB each.) Hi, You may know that I'm working on benchmarks. I regenerated all benchmark results of speed.python.org using performance 0.3.2 (benchmark suite). I started to analyze results. All results are available online on the website: https://
