The maximum forwarding rate I got from vmxnet3 pmd with l2fwd is only 2.5 to 2.8 Gbps. This is in contrast with ixgbe pmd with which I could easily achieve 10 gbps forwarding rate. With the original vmxnet3 driver (non pmd), I could also achieve close to 10 gpbs with multiple iperf. But I can never achieve that rate with vmxnet3 pmd... So basically vmxnet3 pmd doesn't seem that fast. Is this a known issue? Thanks, -Hyunseok
