Dear OVS community, First of all, I am not sure if this is the right place for this question but I think it is worth to try.
I installed openstack pike with ovs supporting the SDN virtual switches and had the impression that my SDN was not fast enough. Please see my configuration below: * Physical compute hosts connected through a 25Gbps network. * Each compute node has 64 cpus and 512 GB RAM. For some reason I could not get more than 10Gbps bandwidth of intra-subnet traffic (no routing) across 2 vms living in same physical host with VXLAN offload configured. I tested the network performance using iperf and iperf3 with multiple threads in parallel. No other vm was running in the system and the vms were only instantiated to run this network performance test so there were no shortage of resources Because the SDN traffic was within same compute node and same network (no routing involved) I am guessing that poor performance has something to do with OVS running in cpu but I have no clue to prove my theory. I am hoping someone in this email list would clarify if I am in the right direction or not and why.
