(Not having the same issue with an Intel E810 using the same exact setup and DPDK version). What would be the proper configuration for mlnx_qos so that I get the best performance for 64bytes frame? (Or perhaps there's some other MLX tool to use??) Please note I disable pause frame, and ethtools shows the following counters increasing: . rx_prio0_bytes: 1272663864199 rx_prio0_packets: 3681438138 rx_prio0_discards: 775995466 tx_prio0_bytes: 72430 tx_prio0_packets: 421 . Only prio0 discards increase for some reason, not sure how to properly configure the card to increase the performance. There are some resources on the internet regarding mellanox configuration, but are all a bit vague on what to do. According to https://fast.dpdk.org/doc/perf/DPDK_21_08_Mellanox_NIC_performance_report.pdf The performance should be pretty much line rate for 64 bytes frame. Thanks -- BR, Filip +48 666 369 823
