So adding the cache to improve the query speed After adding @MEMOIZE to the following function https://github.com/openstack/keystone/blob/master/keystone/identity/core.py#L580. First query time almost costs 50 seconds,but second query time later it only costs 7 seconds. So it is very necessary to improve this feature To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-archive/+bug/1582585/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : yahoo-eng-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
