Winsock Stress Test - OpenClose (Compact 2013)
3/26/2014
The Winsock Stress Test strains Winsock and networking functionality by performing a large number of socket operations. The socket operations performed by this test may also stress the remainder of the networking stack, for example, when receiving and sending large amounts of data.
This test opens and closes a large number of sockets. You can specify the number of sockets to open and close and whether the sockets are bound, connected, or used in data transfers. You can also specify the application that launches the client thread, the server thread, or both.
You can run this test from a single command line or between two separate devices. You should run the server thread before or in the same command line as the client thread.
