TCP throughput vs. Delay and Window Size

TCP throughput (bits per second) = Window Size (bits) / Latency (seconds)

Optimal TCP Window Size (bits) = Bandwidth (bits per second) * RTT latency (seconds)

Maximum RTT latency for desired throughput = Window size (bits) / Desired throughput (bits per second)

some good explanations can be found here
