Link speed: 1Gbps. Maximum throughput I get is 50% with 1470 Bytes. = With 512B pkt sizes, throughput drops to 282 Mbps. Tried using KNI loopback modes (and traffic from Ixia), but no change in th= roughput. KNI is running in single thread mode. One lcore for rx, one for tx and ano= ther fir kni thread. Is the result expected? Has anybody got better numbers? Appreciate for in= put and relevant info. Thanks, -Vithal
