How can I increase the throughput/bandwith of my virtual network?
Solution 1:
You seem to have solved the tool issue, I might add that for maximum performance inside a vSwitch in VMware, make sure that you're running the latest vmtools and VMXNET3 adapters (the legacy e1000 adapters are kinda slow comparatively).
Here's an interesting comparison; http://rickardnobel.se/vmxnet3-vs-e1000e-and-e1000-part-2/
