# `--limit-rate`
|
||
|
|
|
||
|
|
Specify the maximum transfer rate you want curl to use - for both downloads
|
||
|
|
and uploads. This feature is useful if you have a limited pipe and you would like
|
||
|
|
your transfer not to use your entire bandwidth. To make it slower than it
|
||
|
|
otherwise would be.
|
||
|
|
|
||
|
|
The given speed is measured in bytes/second, unless a suffix is appended.
|
||
|
|
Appending 'k' or 'K' counts the number as kilobytes, 'm' or 'M' makes it
|
||
|
|
megabytes, while 'g' or 'G' makes it gigabytes. The suffixes (k, M, G, T, P)
|
||
|
|
are 1024 based. For example 1k is 1024. Examples: 200K, 3m and 1G.
|
||
|
|
|
||
|
|
The rate limiting logic works on averaging the transfer speed to no more than
|
||
|
|
the set threshold over a period of multiple seconds.
|
||
|
|
|
||
|
|
If you also use the --speed-limit option, that option takes precedence and
|
||
|
|
might cripple the rate-limiting slightly, to help keeping the speed-limit
|
||
|
|
logic working.
