A TCP/IP-based network with a minimum network bandwidth of 100 megabits per second is recommended for running WCAT. During a WCAT test, the controller and clients communicate by using Windows Sockets in conjunction with Transmission Control Protocol (TCP).
A small network bandwidth is likely to affect the results of the test. Also, before running a WCAT test verify that the network adapters on all participating computers are working properly and that they do not limit the performance of the computers’ connections to the network.
