Description

The TCP_SEND_BUFFER option specifies the size of the TCP send buffer used for socket connections.

TCP_SEND_BUFFER provides the ability to tune TCP data transfer performance between a manager component and a server component started by the Universal Broker. See /wiki/spaces/UA73/pages/3771426 for a description on using this option to tune data transfer performance.

Universal Broker will instruct TCP to set the socket send buffer to the specified size. The actual TCP send buffer size used is determined by TCP based on its configuration. The TCP configuration can limit the buffer size to a maximum value for example.
