 FIX: TCP/IP Nagle algorithm for Microsoft Message Queue Server can be disabled Symptoms. When sending messages with Microsoft Message Queue and TCP/IP as the transport protocol, there may be a delay of approximately 000ms before the packet is sent over the network. This is because the Windows TCP/IP stack uses the Nagle algorithm. By studying congestion control techniques used in TCP implementation software and network hardware we can better comprehend the performance issues of packet Some of these incidents have been a result of algorithms used or not used in the Transmission Control Protocol (TCP) [00].
