Hi, I use iperf to test the 10G performance of OVS bridge with vlan tag added on the vport for the VMs.
On each machine, the OVS bridge are created on the Intel 82599 10G NIC. I found the performance drops significantly when I added vlan tag on the vport of both VMs. no vlan tag: 9.47 Gbps add vlan tag: 3.96 Gbps Is this a normal behavior after adding vlan tag to the packet header? Thanks. - Hui Kang
