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
There are two Gigabit Ethernet connections on the P5B Deluxe motherboard; one using the PCI Express bus and the other using the PCI bus. By using the PCI bus, the second Gigabit networking connection was only capable of reach 580 Mb/s. But since we have at least one full Gigabit connection, the secondary NICs slower speeds are fully acceptable.
