+# NAME
+
+CURLOPT_LOW_SPEED_LIMIT - low speed limit in bytes per second
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOW_SPEED_LIMIT,
+                          long speedlimit);
+~~~
+
+# DESCRIPTION
+
+Pass a long as parameter. It contains the average transfer speed in bytes per
+second that the transfer should be below during
+CURLOPT_LOW_SPEED_TIME(3) seconds for libcurl to consider it to be too
+slow and abort.
+
+# DEFAULT
+
+0, disabled
+
+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
+    /* abort if slower than 30 bytes/sec during 60 seconds */
+    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_TIME, 60L);
+    curl_easy_setopt(curl, CURLOPT_LOW_SPEED_LIMIT, 30L);
+    res = curl_easy_perform(curl);
+    if(CURLE_OPERATION_TIMEDOUT == res) {
+      printf("Timeout.\n");
+    }
+    /* always cleanup */
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
