If a download exceeds this \fImaxspeed\fP (counted in bytes per second) the transfer will pause to keep the 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 \fImaxspeed\fP to a value lower than \fICURLOPT_BUFFERSIZE(3)\fP, libcurl might download faster than the set limit initially. This option does not affect transfer speeds done with FILE:// URLs. .SH DEFAULT 0, disabled .SH PROTOCOLS All but file:// .SH EXAMPLE .nf 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); } .fi .SH AVAILABILITY Added in 7.15.5 .SH RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. .SH "SEE ALSO" .BR CURLOPT_MAX_SEND_SPEED_LARGE "(3), " CURLOPT_LOW_SPEED_LIMIT "(3), "
