Nice! For the record, I'll be giving a talk in PyCon Ireland about Codespeed. Would you mind me citing those tweets and screenshots, to highlight usage on speed.python.org? You mentioned new more reliable vs old results. How close are we to have an stable setup that gives us benchmarks numbers reg

Re: [Python-Dev] Benchmarks: Comparison between Python 2.7 and Python 3.6 performance

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
