Public bug reported: Hi, I deploy a new OpenStack cluster OpenStack (version Yoga, Victoria), neutron using "Networking-ovn". Then, I create 2 VM (VM is installed by iperf3 tool) on the same network, on the same compute node. I test bandwidth between 2 VM, and the result is: - Bandwidth is 7 Gbps when the port of the VM has a Security Group. - Bandwidth is 18 Gbps Gbps when the port of the VM doesn't have a Security Group.
Meanwhile, I deploy a new OpenStack cluster OpenStack (version Yoga, Victoria), neutron use "OpenvSwitch". Then, I create 2 VM (VM is installed by iperf3 tool) on the same network, on the same compute node. I test bandwidth between 2 VM, and the result is: - Bandwidth is 18 Gbps when the port of the VM has a Security Group. - Bandwidth is 18 Gbps Gbps when the port of the VM doesn't have a Security Group. ---> I noticed that the bandwidth between 2 VM (the port of the VM has a Security Group) is very low when deploying Neutron using Networking-OVN ** Affects: networking-ovn Importance: Undecided Status: New ** Affects: neutron Importance: Undecided Status: New ** Tags: ovn ** Also affects: networking-ovn Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
