It gives close to line rate however lesser than plain dpdk running in guest. And we know the root-cause. Venky, In very early days did highlighted in his report. But that(s) a different problem and I guess odp-dpdk work likely to address them. However, Hongbo can anyways create a lava setup where odp-dpdk (on x86 box, using dpdk favorable nic) doing l2fwd at guest. And that setup shows result in pps, vcpu-utilization and if possible -rtt (i guess: its not there, we'll have to write em).
