| + | Turn on the TCP_NODELAY option. |
| + | |
| + | This option disables the Nagle algorithm on TCP connections. The purpose of |
| + | this algorithm is to minimize the number of small packets on the network |
| + | (where "small packets" means TCP segments less than the Maximum Segment Size |
| + | 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. |
| curl sets this option by default and you need to explicitly switch it off if | |
| you do not want it on (added in 7.50.2). | |
