Reading Time: 4 minutes One important concept of virtual networking is that the virtual network adapter (vNIC) speed it’s just a “soft” limit used to provide a common model comparable with the physical world. For this reason, the Intel e1000 and e1000e vNIC can reach a real bandwidthbigger than the canonical1 Gpbs link speed. But what about the vmxnet3 vNIC that can advertise also the 10 Gpbs link speed. What is the real bandwidth of this adapter?
