Methods and properties described further down are specific to ESP8266. They are not covered in Arduino WiFi library documentation. Before they are fully documented please refer to information below.

setNoDelay

setNoDelay(nodelay)

With nodelay set to true, this function will to disable Nagle algorithm.

This algorithm is intended to reduce TCP/IP traffic of small packets sent over the network by combining a number of small outgoing messages, and sending them all at once. The downside of such approach is effectively delaying individual messages until a big enough packet is assembled.

Example:

clinet.setNoDelay(true);
