Thanks. As expected for calls to C function for both PEPs and master perform about the same, as they are using almost the same calling convention under the hood. As an example of the advantage that a general fast calling convention gives you, I have implemented the vectorcall versions of list() and range()I added benchmarks for PEP 590:https://gist.github.com/jdemeyer/f0d63be8f30dc34cc989cd11d43df248
https://github.com/markshannon/cpython/compare/vectorcall-minimal...markshannon:vectorcall-examplesWhich gives a roughly 30% reduction in time for creating ranges, or lists from small tuples.
