CURLOPT_TCP_NODELAY(3)					     curl_easy_setopt options					    CURLOPT_TCP_NODELAY(3)

NAME

       CURLOPT_TCP_NODELAY - set the TCP_NODELAY option

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_NODELAY, long nodelay);

DESCRIPTION

       Pass a long specifying whether the TCP_NODELAY option is to be set or cleared (1 = set, 0 = clear). The option is set by default. This will
       have no effect after the connection has been established.

       Setting this option will disable TCP's Nagle algorithm. The purpose of this algorithm is to try to minimize the number of small packets	on
       the network (where "small packets" means TCP segments less than the Maximum Segment Size (MSS) for the network).

       Maximizing the amount of data sent per TCP segment is good because it amortizes the overhead of the send. However, in some cases small seg-
       ments may need to be sent without delay. This is less efficient than sending larger amounts of data at a time, and can contribute  to  con-
       gestion on the network if overdone.
