loadHTML＆loadHTMLFile，哪一個更快？

Question

這兩者之間，哪一個更快？直接獲取內容由loadHTMLFile或cURL，然後再傳遞到loadHTML

$doc = new DOMDocument(); 
@$doc->loadHTMLFile($url); 

或者

$doc = new DOMDocument(); 
$ch = curl_init(); 
$timeout = 500; 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout); 
$data = curl_exec($ch); 
curl_close($ch); 
@$doc->loadHTML($data);
