Our own = DPDK app (a Load Balance app) is used and UDP 64 bytes is generated by = tester. We found that when we generated about 2.6Mpps UDP traffic for 1 core and = 2 port setting testbed, our app starts to drops packets. However, the = strange issue is we cannot see any imissed or error statistics from DPDK = layer. I saw the Mellanox test performance result in = https://fast.dpdk.org/doc/perf/DPDK_18_11_Mellanox_NIC_performance_report.= pdf = and how do you find packet lose? Is there a bug in statistic = calculation in DPDK or there is another way to trace packet drop? Retrieve DPDK statistics is also used for Intel NIC and the behavior is = right. it should not be wrong for our usage in our own app. Any suggestions would be welcomed. Thanks very much!
