[ovs-discuss] Transfer Data rate is slowly

Of course there are many possible reasons for this such as the virtual
machine not having sufficient resources in CPU, RAM and Storage IOPS.

You probably want to use IPERF to test network throughput...

http://sourceforge.net/projects/iperf/

Do it first on your bare metal machine to the VM and that will show you
what the native throughput of the OVS is internally.  Then you can run it
over your network.

Test 1: VM through OVS to Host <-- test the OVS
Test 2: Host through network to another bare metal box <-- test the network
Test 3: VM through OVS through network to another bare metal box <-- test
both OVS and network

By comparing these 3 results you can make a decision as to the performance
impact of the OVS to a virtual machine.
