    Mellanox ConnectX-5 adapter speed 650MB/s only

    rahulgoradia

      Helllo,

      I have two Mellanox Connectx-5 adapters connected back to back. Link speed shows 40Gbps. I am using widows server 2016. Tried with different PCIe slots and tested with iperf3. But in case of TCP speed reaches up to 650 MB/s only and in UDP it only achieves nearby 450 MB/s.

      I am sure I am missing out some setting but can not figure out what.

      Can anybody help me in this case?
