This is Python 3.6 -> 3.9 compiled to Intel running under Rosetta 2.

For Rust I am running the ARM toolchain that was recently released, so no Rosetta involved at all.

Do you think moving from python 3.6 to 3.6 had any impact whatsoever? I'm surprised by such a large improvement in performance as other reports I read indicated similar-to-slightly-worse python performance of M1 vs x86.

I run test suite across those Python's. So Python 3.6, 3.7, 3.8, and 3.9 using tox to drive the automation to test against all of those versions to validate compatibility and that nothing breaks.

So there is no moving anything. Python compiled using pyenv for the Intel platform.

Which reports are you reading? Are they using C libraries or doing heavy math computation that is not CPU bound because there's no optimized ARM version yet?

Okay, I'm not finding any benchmark that supports the idea of a slowdown, so probably I remembered some rumour I read on twitter or reddit.

What I am finding now is that python is working more than fine on M1, be it through rosetta or native code, which is consistent with your experience.

Also to clear things a bit, I parsed your "3.6 -> 3.9" as meaning that you had moved from Py36 on intel to Py39 on apple, which is why I asked if maybe there were speedups or differences from moving to 3.9.
