CURLOPT_TCP_NODELAY(3) curl_easy_setopt options CURLOPT_TCP_NODELAY(3)NAMECURLOPT_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 cleared 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.
