 So what is this about? This is about the D0-200 water lilyzation. We set up this demo for the water lilyzation on D0-2002. So what is happening here? Here we draw a water VM on this D0-2002 and then we send the packet to something like OS and we call it US. So the VM sends the packet to the US and the packet is out from here to this X86. So we want to get a higher performance. So actually if we only use OS and this one, the performance is 50,000 pps. If we use US on it, we get a 10,000 of this. So it's twice as high.
