I didn't followed last development around the GIL. Can you explain me why Python should have its own scheduler whereas each OS has already its own scheduler? The OS has useful informations to help scheduling that Python doesn't have. Linux and FreeBSD schedulers are faster each year since... 5 years?, especially with multiple CPU/cores. -- Victor Stinner http://www.haypocalc.com/ _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
