Network Interface Tests
Our network tests use the ntttcp application distributed by Microsoft for testing network controller’s efficiency. The program creates a number of threads from a server machine to spit data at the test machine at up to Gigabit speeds. Both maximum throughput and CPU utilization are tested.
Network Interface Test — Max Throughput
Network Interface Test — CPU Utilization
While both network bandwidth and CPU usage is nearly the same on both platforms, the CPU utilization appears to be MUCH higher under Vista than it was on Windows XP.
