hello All, i have contrail 3.0.* with DPDK vrouter running on 2 compute nodes with 1Gbx100 hugepages and 6 dedicated CPU for the DPDK vrouter process in 1 NUMA node.
Created 2xUbuntu (16.04) 40Gb hugepage enabled vm with 6 dedicated VCPU in same compute nodes (Jumbo frames enabled) when performing iperf between the vms i get a through put of 2 Gbps where as vms on Non DPDK nodes i am getting 9Gbps. I assume vms running on DPDK nodes are not optimized and probably i need to compile in DPDK Libraries and DPDK application to get improved performance on Ubuntu16.04. My question is : with out DPDK libraries in guest why is the performance too low.Since qemu process is set to share memory and i assume with this option all packets ll be copied to guest memory by the dpdk vrouter. Thanks for your help Regards, Kev
