Nagle's algorithm coalesces small writes while data are unacknowledged, permitting another send when a full TCP segment can be formed or the outstanding data have been acknowledged. It reduces tiny transmissions but can add delay.
Nagle's algorithm is a network optimization technique designed to improve the efficiency of TCP/IP networks by reducing the number of small packets sent over the network. It was developed by John Nagle in 1984. ### Purpose The algorithm aims to solve the problem of sending small packets or "tinygrams," which can lead to inefficiencies when a large number of small packets are transmitted over a network.
