Benchmark on macOS Mojave (10.14.2), x86_64: $ ./python.exe -m perf compare_to fork_exec.json posix_spawn.json Mean +- std dev: [fork_exec] 2.79 ms +- 0.06 ms -> [posix_spawn] 1.64 ms +- 0.03 ms: 1.70x faster (-41%) The speedup is "only" 1.7x faster, it's less impressive. Maybe fork()+exec() is more efficient on macOS than on Linux. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue35537> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
