I finally cleaned up my benchmark script, which feels like a big hack. I should really learn to use pyperf or something. Inspired by your comment about 3.8 on the Mac I tried my Ubuntu installation's stock 3.8. I get a small degradation (~0.5%) for powers of two and 4-5% speedups just below powers of two and for shuffle. (This is under the slightly strange situation where _randbelow is using the main branch code but everything else in the class is imported from 3.8.) _randbelow_without_getrandbits() is consistently (if only slightly) faster, as you would expect for cases that are basically guaranteed to call self.random() only once. I am impressed (if not necessarily surprised) by the variation between builds, especially with my friend's ARM builds which reached nearly 20% for one case. So I completely understand if it's less uncertain just to pass. Thanks for your attention, in any event! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45976> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
