Not quite. I wrote this up, back in November: http://etherpad.openstack.org/keystone-scalability Since then, of course, Keystone has gone through some major cleanups that have improved its efficiency, but, as Vish pointed out in the other thread, every service still has to hit Keystone to verify a given token, which makes Keystone have the highest number of hits for any given operation…which in turn makes it *the* most likely bottleneck. -- Kevin L.
