(I'm hoping that OpenStack will now automatically skip authentication and therefore improve performance, even though the "secret" keys and other "cephx authetnication" keyrings are still left in the OpenStack and/or virsh configuration files.) OpenStack won't need to be reconfigured, Ceph will just not use the authentication information. > (I've noticed a slight performance drop between 2 different CEPH deployments. There were a couple variables that were different between the 2 deployments, one of which was cephx authentication -- how much of a performance penalty do people think CEPHX authentication incurs?) I'm not sure but I would be surprised if it makes a significant difference.
