I don’t think we can safely assume Python 3.7 has the same performance, actually. A lot has changed.
I'm not denying that some things have changed. Rather, I claim that those changes wouldn't invalidate the benchmarks.
I am comparing calls through tp_call (A) versus optimized call paths (B). I only need to assume that the speed improvements to (A) between 2.7 and 3.7 are not bigger than the speed improvements to (B).
Most optimizations which have been done in Python 3.x target (B). In fact, I'm not aware of any optimization to (A) apart from maybe some minor code improvements. So I think it's a relatively safe assumption that the speed difference between (A) and (B) did not decrease from 2.7 to 3.7.
