STINNER Victor added the comment: Result of attached bench_recursion-2.py comparing before/after the 3 changes reducing the stack consumption:
test_python_call: Median +- std dev: [a30cdf366c02] 512 us +- 12 us -> [6478e6d0476f] 467 us +- 21 us: 1.10x faster (-9%) test_python_getitem: Median +- std dev: [a30cdf366c02] 485 us +- 26 us -> [6478e6d0476f] 437 us +- 18 us: 1.11x faster (-10%) test_python_iterator: Median +- std dev: [a30cdf366c02] 1.15 ms +- 0.04 ms -> [6478e6d0476f] 1.03 ms +- 0.06 ms: 1.12x faster (-10%) At least, it doesn't seem to be slower. Maybe the speedup comes from call_function() inlining. This function was probably already inlined when using PGO build. The script was written by Serhiy in the issue #29227, I modified it to use the Runner.timeit() API for convenience. ---------- Added file: http://bugs.python.org/file46249/bench_recursion-2.py _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28870> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
