    openstack vm and sr-iov vs non-sriov performance

    ranjitshs

      Hello

       

      I am doing performance testing with VM using open stack and sr-iov technology.

       

      Test scenario info:

      • HOST TO VM
      • 4 type of packet (64,100,220,1500)
      • The time for each run is 10s.
      • TCP packet
      • VM is having Ubuntu OS and 768 MB RAM
      • iperf is used to calculate bandwidth

       

      Non-SRIOV Test - performed with 6 VMs running (Using neutron + openvswitch plugin )

      SRIOV Test – performed with 3 VMs running. (Using neutron + SR-IOV port. NIC info: Intel Corporation Ethernet Controller 10-Gigabit X540-AT2)

      Performance bandwidth for both case 'WIthout SR-IOV' and 'SR-IOV' are almost same.

      So i would like to know in which scenario SR-IOV will give better performance.

      if you feel we are missing some thing in test result/ test scenario , then let me know.

       

      Thanks
