CURLOPT_MAX_RECV_SPEED_LARGE(3)                       Library Functions Manual

NAME
       CURLOPT_MAX_RECV_SPEED_LARGE - rate limit data download speed

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAX_RECV_SPEED_LARGE,
                                 curl_off_t maxspeed);

DESCRIPTION
       Pass a curl_off_t as parameter. If a download exceeds this maxspeed
       (counted in bytes per second) the transfer pauses to keep the average
       speed less than or equal to the parameter value. Defaults to unlimited
       speed.

       This is not an exact science. libcurl attempts to keep the average
       speed below the given threshold over a period time.

       If you set maxspeed to a value lower than CURLOPT_BUFFERSIZE(3),
       libcurl might download faster than the set limit initially.

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

DEFAULT
       0, disabled

PROTOCOLS
       All

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode ret;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
           /* cap the download speed to 31415 bytes/sec */
           curl_easy_setopt(curl, CURLOPT_MAX_RECV_SPEED_LARGE, (curl_off_t)31415);
           ret = curl_easy_perform(curl);
         }
       }

AVAILABILITY
       Added in 7.15.5

RETURN VALUE
       Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION
       if not.
