    Intel 710 4 port high RX discard rate when more than 1 port is receiving data

    namf1az

      Running DPDK 18.08 (latest stable) and cannot achieve > 6-7 Gbps RX rate (per-port) without seeing increasing "discard" rate.

      All relevant configuration values are at maximum (rx ring size @ 4096).

      Specific test is using 2 ports at 8Gb each but cannot get beyond ~13.5 Gbps (or 6.8 per port).

       

      PS.  The 710 is in PROMISCUOUS mode.  Does P mode negatively affect multi-port performance?
