    ConnectX-2 and ESXi 6.5 slow speed

    michaelshteinberg

      Hi,

       

      I have ConnectX-2 card in my ESXi 6.5 server

       

      Added this card to FreeNAS (VM) and OpenMediaVault (VM)  as VMXNET3 adaptor

       

      When i test the speed between the FreeNAS/OMV (VM) and Windows (PC) i get only 200-300 MBytes/sec

      When i test the speed between the FreeNAS (VM) and OMV (VM)  i get  4000-5000 MBytes/sec - on the same vSwitch

      When i test the speed between the Windows (PC) and Windows (PC) i get only 900-1000 MBytes/sec - Result that i expected to be in ESXi

      Tested speeds with iperf

      What can be the problem? drivers?

       

      By the way when i passthrough the card to FreeNAS, the FreeNAS doesn't recognize it.

       

      Thank you for help
