(old name: CURL.SetOptionMaxSendSpeedLarge)


Parameter Description Example value
curl The CURL session handle. $curl
Value Maximum sending speed in bytes per second. 50000


Returns "OK" on success.


Sets the maximum sending speed.
If an upload exceeds this speed (counted in bytes per second) on cumulative average during the transfer, the transfer will pause to keep the average rate less than or equal to the parameter value. Defaults to unlimited speed.
Useful if you have a limited pipe and you'd like your transfer not to use your entire bandwidth.
Slowing down the transfer speed is also useful for lowering CPU consumption during transfers.
