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.
