We are upgrading 6wind from 6wind 4.13->4.17, with DPD= K upgrading from 16.04->17.05. We use AVP PMD driver. >>From the performance test result, the CPU load of RX core increase from 72%= to 94% under same pps. The bitrate decreased from 9800M to 9000M, limitati= on is also in RX core. The difference is only 6wind software and DPDK code. Do you have some test result for DPDK AVP PMD driver for release 16.04 and = 17.05? Do you have some suggestion to increase the AVP PMD driver performance? Is = the later version have any improvement for AVP? Waiting for your response. Thank you! Br, Wang Qihua
