Description

Defines the length of delay in sending acknowledgements for transacted messages.

Message Queuing (also known as MSMQ) 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 the number of seconds specified in the value of this entry.

This 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.

This entry does not exist in the registry by default. You can add it by using the registry editor Regedit.exe.
