15 Pass a curl_off_t as parameter. If a download exceeds this maxspeed
16 (counted in bytes per second) the transfer will pause to keep the speed
17 less than or equal to the parameter value. Defaults to unlimited speed.
18
19 This is not an exact science. libcurl attempts to keep the average
20 speed below the given threshold over a period time.
21
22 If you set maxspeed to a value lower than CURLOPT_BUFFERSIZE(3),
23 libcurl might download faster than the set limit initially.

25 This option does not affect transfer speeds done with FILE:// URLs.
