Hi All, Toady I met one vrotuer forwarding performance declining issue. Could some experts help me analyze it? Topology: Openstack version is kilo version , contrail version is R 2.2 and iperf version is 2.0. I uesd the 2 VMs in the same computer node to verify the vrouter forwarding performance. The VM machine is Ubuntu 12.04 OS. I initiated the iperf server in the VM A, and iperf client in the VM B. Then the TCP Traffic can get 9.0+ Gbps throughput. But sometimes TCP traffic could only 1.0+ Mbps and it could recover until I restart the supervisor-vrouter service in the computer node. I could not find the drop statics in the tap interface. I thought that the communication between the two VMs in the same computer node and there is no encapsulation and decapsulation in the forward process. If someone know the reason or could provide the thread , please let me know.
Thanks Junwei Wang
