    The TCP Window size determines how much data is transferred between the two hosts before an acknowledgement is sent to say that everything was OK.  If your TCP Window size is say, 10KB, then the source computer will send a maximum of 10KB, and wait for a response from the target computer, before sending the next 10KB.

    The bigger the window, the faster the throughput, because the less confirmations are required from the other party.  Your TCP Window size should not exceed 64 KB.

    I have written an article which helps test network performance - and it talks about the TCP Window size in there giving examples of how it can affect performance -
