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 node-
       lay);

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 conges-
       tion on the network if overdone.
