Property setter documentation:

Sets the SocketOptions#SO_RCVBUF SO_RCVBUF option to the specified value for this Socket. The SocketOptions#SO_RCVBUF SO_RCVBUF option is used by the platform's networking code as a hint for the size to set the underlying network I/O buffers.

Increasing the receive buffer size can increase the performance of network I/O for high-volume connection, while decreasing it can help reduce the backlog of incoming data.

Because SocketOptions#SO_RCVBUF SO_RCVBUF is a hint, applications that want to verify what size the buffers were set to should call #getReceiveBufferSize().

The value of SocketOptions#SO_RCVBUF SO_RCVBUF is also used to set the TCP receive window that is advertized to the remote peer. Generally, the window size can be modified at any time when a socket is connected. However, if a receive window larger than 64K is required then this must be requested <B>before</B> the socket is connected to the remote peer. There are two cases to be aware of: <ol> <li>For sockets accepted from a ServerSocket, this must be done by calling ServerSocket#setReceiveBufferSize(int) before the ServerSocket is bound to a local address.</li> <li>For client sockets, setReceiveBufferSize() must be called before connecting the socket to its remote peer.</li></ol>
