I'm skeptical about "50% gain": I want to see a working implementation and reproduce benchmarks myself to believe that :-) As you wrote, the cost of function costs is unlikely the bottleneck of application. Sorry, I didn't read all these PEPs about function calls, but IMHO a minor speedup on micro benchmarks must not drive a PEP. If someone wants to work on CPython performance, I would suggest to think bigger and target 2x speedup on applications. To get to this point, the bottleneck is the C API and so we have to fix our C API first. http://vstinner.readthedocs.io/python_new_stable_api.html Victor _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
