緩慢的mysql數據加載

Question

我的問題是，我的網頁加載速度很慢....（2-3秒） 我測試了問題的來源，我看到的是該部分：$ query = mysql_query .... ..

這裏是頁：

require_once('config/db_config.php'); 
require_once 'class/PHPTemplate.class.php'; 
session_start(); 
//Connect to mysql server 
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); 
if(!$link) { 
    die('Failed to connect to server: ' . mysql_error()); 
} 
//Select database 
$db = mysql_select_db(DB_DATABASE); 
if(!$db) { 
    die("Unable to select database"); 
} 
$query = mysql_query("SELECT * FROM pages WHERE url_address='Skarabeol'"); 
$numrows = mysql_num_rows($query); 
if($numrows!=0) { 
    while ($row = mysql_fetch_assoc($query)) { 
     $content=$row['content']; 
     $title=$row['title']; 
    } 
} else {Echo "Page not found!";} 
$rows = array(
    array(1.1, 1.2, 1.3), 
    array(2.1, 2.2, 2.3), 
    array(3.1, 3.2, 3.3), 
    array(4.1, 4.2, 4.3) 
); 
$tpl = new PHPTemplate(); 
$tpl->add('title', $title); 
$tpl->add('content', $content); 
$tpl->add('current_year', date('Y')); 
//$tpl->add('rows', $rows); 
//$tpl->add('rows_count', count($rows)); 
$tpl->load('footer', 'tpl/footer.tpl'); 
$tpl->display('tpl/page.tpl'); 
?> 

而且它會加載一個模板文件（我沒有測試MySQL連接，它工作得很好）。

這裏是你想看到它的情況下配置文件...

define('DB_HOST', 'localhost'); 
    define('DB_USER', 'xxxxxxx'); 
    define('DB_PASSWORD', 'xxxxxxxxxx'); 
    define('DB_DATABASE', 'xxxxxxxxx'); 

什麼，我做錯了什麼？

請讓我知道，如果你需要我給你看別的東西....提前致謝！

嘗試使用分析來查看SQL統計信息。
