CoreConnectionPNames.TCP_NODELAY='http.tcp.nodelay': determines whether Nagle's algorithm is to be used. Nagle's algorithm tries to conserve bandwidth by minimizing the number of segments that are sent. When applications wish to decrease network latency and increase performance, they can disable Nagle's algorithm (that is enable TCP_NODELAY. Data will be sent earlier, at the cost of an increase in bandwidth consumption. This parameter expects a value of type java.lang.Boolean. If this parameter is not set, TCP_NODELAY will be enabled (no delay).
CoreConnectionPNames.SOCKET_BUFFER_SIZE='http.socket.buffer-size': determines the size of the internal socket buffer used to buffer data while receiving / transmitting HTTP messages. This parameter expects a value of type java.lang.Integer. If this parameter is not set, HttpClient will allocate 8192 byte socket buffers.
