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
All of the network interface’s perform pretty well here, though the ATI reference board’s is based on an external chip, not an integrated controller. The disadvantage of this is obviously the higher CPU utilization.
