Pretty sure Python 3 has had better performance since 3.5 or so?

I still see benchmarks from bilingual projects which show py2 being faster, such as http://falconframework.org/#sectionBenchmarks

YMMV. The benchmark you mentioned used 3.6.

https://hackernoon.com/which-is-the-fastest-version-of-pytho... has a benchmark that includes 3.7.
