Hi, When we did our testing a few months ago we saw the same thing with the degradation of the performance. Keystone was a notable bottleneck. Thanks Gary

Why the performance of Stein concurrent creation of VM is not as good as that of Ocata? Create 250 VMs concurrently, the O version only needs 160s, but the S version needs 250s.
Openstack's execution environment is complicated. It's hard to say O is faster than S from the architecture viewpoint. Are you sure two systems' running environment are totally the same for comparision? including the software, hardware, network connection etc.
