By the way, strace has a '-T' flag that can be used to measure the time spent in syscalls (but for a mmap/mremap/munmap it won't be significant). > However, I do think that doing the performance testing before deprecating > the previous interface would have been a good idea... > Once again: subprocess.Popen is actually faster than os.pipe to create a subprocess. Just don't pass shell=True. Unless you're spawning shell scripts, but in that case subprocess' overhead is definitely not biggest problem. ---------- _______________________________________ 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
