Description

The TCP_NO_DELAY option specifies whether or not to use TCP packet coalescing.

The packet coalescing algorithm, which can delay the sending of small amounts of data over the network, is designed to improve network congestion. However, since it can have a significantly negative effect on the performance of UDM, TCP_NO_DELAY specifies - by default - not to use TCP packet coalescing.
