Facebook API发布照片/状态更新非常缓慢

我将用户存储在数据库中。我在循环中用这些函数调用它们，但每个帖子大约需要5到15秒。不是数据库代码，只是发布功能使它变慢了。这不是所有的代码，但在我看来是最重要的。

现在我看了代码，我想知道是否需要在循环中调用函数GetContentsUsingCurl（）。有人帮我写了这个代码，但它很慢所以我试着把它收紧。

示例代码在循环中调用这些函数：

/// loop code
{
PostPhoto($fbId, $access_token);
PostText($fbId, $access_token);
}

我的问题：我能以某种方式让它更快吗？

function PostPhoto($fbId, $access_token)
    {
        global $PIC_URL;
        global $PIC_CAPTION;
        $url = 'https://graph.facebook.com/' . $fbId . '/photos';
        $attachment =  array(
                'access_token'  => $access_token,
                'url'           => $PIC_URL
        );
        $result = GetContentsUsingCurl($url, $attachment);
        $result = json_decode($result, TRUE);
        if( isset($result['error']) ) 
        {
            echo "Error Message: ".$result['error']['message']."<br/>";
            echo "Error Type: ".$result['error']['type']."<br/>";
            echo "Error Code: ".$result['error']['code']."<br/>";
        }
        else
        {
            echo "<pre>";
            echo "Photo posted successfully!<br/>";
        }
    }
    function PostText($fbId, $access_token)
    {
        global $TWEET_URL;
        global $TEXT_MESSAGE;
        global $AD;
        $url = 'https://graph.facebook.com/' . $fbId . '/feed';
        $tweet = GetContentsUsingCurl($TWEET_URL, "");
        $tweet = "'"".trim($tweet)."'"'n'n"; 
        $attachment =  array(
                'access_token'  => $access_token,
                'message'  => $tweet.$TEXT_MESSAGE.$AD
        );
        $result = GetContentsUsingCurl($url, $attachment);
        $result = json_decode($result, TRUE);
        if( isset($result['error']) ) 
        {
            echo "Error Message: ".$result['error']['message']."<br/>";
            echo "Error Type: ".$result['error']['type']."<br/>";
            echo "Error Code: ".$result['error']['code']."<br/>";
        }
        else
        {
            echo "<pre>";
            echo "Feed posted successfully!<br/>";
        }
    }

    function GetContentsUsingCurl($url, $attachment)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $attachment);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $result = curl_exec($ch);
        curl_close ($ch);
        return $result;
    }
