I am doing performance testing with VM using open stack and sr-iov technology.
Test scenario info:
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.
Thank you for the post. We will check on this then update you.
