These stats don't stand out as unusual to me. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] [ovn/ovs] hit and miss
Hi, I am using ovn with openstack and using geneve tunnel as an overlay. I have two compute nodes and I am trying to test network performance via iperf3 between VMs. I have configured 9000 on tunnel interface and VM has 1500 mtu. The network performance with 1500mtu is 3.5Gbps with --bidir switch and with 8942 I am having 7.5Gbps with --bidir between VMs on different compute hosts. I am net using dpdk and or any other offloading. I have checked ovs-dpctl stats.
