+Pass a long specifying your preferred size (in bytes) for the receive buffer

+This size is by default set as big as possible (CURL_MAX_WRITE_SIZE), so it
+only makse sense to use this option if you want it smaller.
.IP CURLOPT_PORT

one specified in the URL or the default port for the used protocol.
