Hello everyone! 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. Security_group and port_security functions are disabled. Among 250 VMs, there are single network card and multi-network card. Using neutron-openvswitch-agent.
