    NVDS throughput limitation

    azizse Lurker


      I there any limitation on NVDS  regarding the throughput.I am using a 10G interface while i am testing troughput on overlay i noticed that the throughput never ecxeeds 5.xGbps.

      Vmware tools is installed on the VMs and VMXnet3 is the network card type.

      Many thanks

          Well actual throughput depends upon on various factors like - Server model (Blade/Rack), MTU (End-End)  and type of network topology involved in the test(L2/L3) and  few vSphere&NSX performance best practices will also let you give maximum throughput Have you ever tested throughput without Genev tunnels ? If you are getting something very limited with that test, you should solve that first and then flip to overlay based testing.

            Hey Screen !

            Thank you for your reply.I have done same test using a VDS (without Geneve tunnel ) and i got 9.x Gbps so the issue is not the physical network and i could reach 9 Gbps with multiple flow.
