I was not able to measure any slowdown on Linux.
We care about Mac OS X though, so even if the contention wasn't as bad on a different OS, the Mac downsides matter. With the GIL updates in place, it would be interesting to see that analysis redone for 2.7/3.2 though. Regards, Nick. P.S. As far as interest in the idea goes, the GIL is one of those areas where it takes a fairly rare combination of interest, expertise and established credibility to propose a change and get assent to it. You'll notice that even Antoine had to resort to the "if nobody objects soon, I'm checking this in" tactic to garner any responses. It's an area where even those with relevant expertise still have to put aside a fair chunk of time in order to properly review a proposed change :) -- Nick Coghlan | ncogh...@gmail.com | Brisbane, Australia --------------------------------------------------------------- _______________________________________________ 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
