API ile 30 veri ms hızında sonuç vermeli. Bu veriyi çekerken yavaşlık söz konusu ise sunucuya geçemeni gerektirecek bir şey yok, sorun ya karşı sunucuda ya da senin kodlarında.

Buyur ufak bir curl fonksiyonu,

/**
* Custom curl function
*
* @param string $url : target URL
* @see source: https://stackoverflow.com/a/14953910
* @return mixed
*/
public function curl($url, $user_agent = null, $returnData = true)
{
$user_agent = $user_agent ? $user_agent : 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1';
$options = array(
CURLOPT_CUSTOMREQUEST => "GET", //set request type post or get
CURLOPT_POST => false, //set to GET
CURLOPT_USERAGENT => $user_agent, //set user agent
CURLOPT_COOKIEFILE => "cookie.txt", //set cookie file
CURLOPT_COOKIEJAR => "cookie.txt", //set cookie jar
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects
CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 20, // timeout on connect
CURLOPT_TIMEOUT => 20, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
);

$ch = curl_init($url);
curl_setopt_array($ch, $options);
$content = curl_exec($ch);
$err = curl_errno($ch);
$errmsg = curl_error($ch);
$header = curl_getinfo($ch);
curl_close($ch);

if ($returnData){
return $content;
}

$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;

return $header;
}


curl('link')['content']; şeklinde deneyebilirsin.
