Because, why? Do you expect the OS to give fairer scheduling between concurrent request threads than Python can do? It seems to me you'll be almost certainly wasting some resources by having multiple non-shareable copies of Python modules, which at hundreds of MB per thread could be a big fraction of the appserver's physical memory. It might still be worth trying just to see what happens though. -- Martin _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : [email protected] Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
