Transmit/Receive Windows and Receive Buffer count

    HP recommends setting a value of 20 for "Maximum Transmit and
    Receive Window" and the value of "Maximum Receive Buffers" to be set
    to no more than ("Maximum Window" * "Maximum Transport Connections")
    for normal network operation in a typical network environment.

    Selecting other values than these can significantly alter the
    behavior of your system and network and should only be done after a
    thorough analysis of your network traffic and application
    requirements.

    High values of "Maximum Receive Buffers" may require considerable
    buffering capacity on your node; therefore, non-paged pool should be
    allocated accordingly. If your node does not have enough non-paged
    pool, "Maximum Receive Buffers" should be set to a smaller value than
    ("Maximum Window" * "Maximum Transport Connections").

    The transport receiver's window is determined by a combination of
    "Maximum  Transport Connections", "Maximum Receive Buffers", and
    "Maximum Window".  During the life of the connection, the receiver
    quota fluctuates  according to the value of ("Maximum Receive
    Buffers" / "Currently Active  Connections"). The credit window sent
    to the remote transmitter may or may not be this quota value,
    depending on the value of "Maximum Window".  If "Maximum Window" is
    set to less than the determined receiver quota,  this value is used
    instead for the credit granted to the remote  transmitter.

    The transmitter of a transport connection uses the credit sent by the
    remote receiver as its transmit window, unless its "Maximum Window"
    is  a lower value. In that case, "Maximum Window" is used for the
    transmitter  window.
