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
