Decision Points for Choosing a Transport

Throughput measures the amount of data that can be transmitted and processed in a specified period of time. Like latency, the chosen transport can affect the throughput for service operations. Maximizing throughput for a transport requires minimizing both the overhead of transmitting content as well as minimizing the time spent waiting for message exchanges to complete. Both the TCP and named pipe transports add little overhead to the message body and support a native duplex shape that reduces the wait for message replies.
