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. +.SH DEFAULT +0 +.SH PROTOCOLS +All +.SH EXAMPLE +TODO +.SH AVAILABILITY +Always +.SH RETURN VALUE +Returns CURLE_OK +.SH "SEE ALSO" +.BR CURLOPT_SOCKOPTFUNCTION "(3), " CURLOPT_TCP_KEEPALIVE "(3), " |
