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.
