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.
The same set of servers, after testing version O, re-install the system, and then test version S. First deployed version O, the operating system is Ubuntu 16.04. Then deploy the version S, the operating system is ubuntu18.04.
The port_security function is disabled.But in the S version environment, adding a lot of flows on br-int. Does this slow down the creation of VM?
The flows is as follows:(for port qvo83b4285e-b5) cookie=0x9ca1d4c6ecdcb31f, duration=257335.826s, table=0, n_packets=0, n_bytes=0, priority=10,icmp6,in_port="qvo83b4285e-b5",icmp_type=136 actions=resubmit(,24) cookie=0x9ca1d4c6ecdcb31f, duration=257335.823s, table=0, n_packets=19, n_bytes=798, priority=10,arp,in_port="qvo83b4285e-b5" actions=resubmit(,24) cookie=0x9ca1d4c6ecdcb31f, duration=257335.831s, table=0, n_packets=95, n_bytes=10680, priority=9,in_port="qvo83b4285e-b5" actions=resubmit(,25) cookie=0x9ca1d4c6ecdcb31f, duration=257335.829s, table=24, n_packets=0, n_bytes=0, priority=2,icmp6,in_port="qvo83b4285e-b5",icmp_type=136,nd_target=fe80::f816:3eff:fe39:1601 actions=resubmit(,60) cookie=0x9ca1d4c6ecdcb31f, duration=257335.826s, table=24, n_packets=19, n_bytes=798, priority=2,arp,in_port="qvo83b4285e-b5",arp_spa=30.0.1.180 actions=resubmit(,25) cookie=0x9ca1d4c6ecdcb31f, duration=257335.841s, table=25, n_packets=114, n_bytes=11478, priority=2,in_port="qvo83b4285e-b5",dl_src=fa:16:3e:39:16:01 actions=resubmit(,60)
