I am using Mellanox ConnectX-4 dual-port 100G NICs (MT27700 Family) and trying to generate packets using DPDK’s pktgen. I was wondering what’s the maximum rate (in pps) that the Mellanox NIC can support.
We could generate 64B packets at most 66.82Mpps even with more than 8 CPU cores. I am not sure whether that’s the maximum limit the NIC can achieve.
We ran the experiment on Ubuntu 18.04, DPDK 18.11, and OFED version 4.5-188.8.131.52.
Could anyone let me know the maximum packet generation speed that the CX-4 NIC can support?
