I ran a microbenchmark on PR 8826: ./python -m perf timeit -s 'fmt=b"%s%s"; args=(b"1", b"x"*(1024*1024))' 'fmt % args' -v -o patch.json $ python3 -m perf compare_to ref.json patch.json Mean +- std dev: [ref] 325 us +- 7 us -> [patch] 36.2 us +- 1.1 us: 8.98x faster (-89%) Ooops, yeah, it's obvious that there was a missed optimization. It's now way faster ;-) ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34436> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
