Antoine Pitrou <pit...@free.fr> added the comment: Interestingly, reducing from the max open file descriptors from 8192 (my default) to 512 halves the runtime and solves the regression:
$ ulimit -n 512 $ ./python bench_subprocess.py pid: 31631 Time: 4903.8 ms So, even though implemented in C, the file descriptor closing logic is still quite costly! ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11314> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
