Nagle algorithm

With the Nagle algorithm, there is a mechanism that prevents the sending of many small data packets with the TCP protocol over IP networks

. For this purpose, the Nagle mechanism first caches the small data packets and concatenates them into a larger data packet. This technique increases the efficiency of packet transmission by relieving the network of an unnecessarily large number of small data packets, thus severely affecting the data transmission rate because each individual mini data packet, even if it is only one byte, must be provided with its own TCP header. In conjunction with the Nagle algorithm, a second algorithm

takes effect that controls the size of the transmission window. Nagle's algorithm was specified by the IETF and is described in RFC 896.
