| REG_DWORD | 0x0 - 0xFFFFFFFE seconds | 0xA (10 seconds) |
Defines the length of delay in sending acknowledgements for transacted messages.
Message Queuing sends an order acknowledgment for the delivered, transacted messages. The value of this entry defines the delay in sending these messages; the receiving computer never sends an order acknowledgment more frequently than once per this number of seconds.
The SeqMaxAckDelay entry provides for batching of messages, which saves unnecessary traffic. Too large a value might cause resending of the messages because the sending computer might think the packets did not arrive. Too small a value might cause more order-acknowledgment packets to be sent.
