Ethernet at 10 Gbps
" The Windows operating system imposes one of the primary bottlenecks at this speed. As one network administrator says, "When we want to stress test our network, we use Linux, not Microsoft." His experience is that contention and file-system-overhead issues within Windows limits 1 GE desktop links to 1.25 Mbps. Even a quad-processor server peaks at 250 to 300 Mbps, with the processor at 100% usage."
So if we cant use the extra bandwidth then whats the point of having it. You can already get 100 Mbps dedicated from a switch to the desktop with old technology
