- .SH NAME
- CURLOPT_TCP_NODELAY \- set the TCP_NODELAY option
- .SH SYNOPSIS
- #include <curl/curl.h>
- CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TCP_NODELAY, long nodelay);
- .SH 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 segments may
- need to be sent without delay. This is less efficient than sending larger
- amounts of data at a time, and can contribute to congestion on the network if
- overdone.
