Plug-in 読込み処理を1回だけに

include/func_base.inc.php 
function include_plugin($mode)
{
    global $cd, $cfg, $plugin;
+   static $done;
+
+   if (isset($done)) return;
+
    if ($handlerDir = @opendir($cd . '/include/user_include/plugins')) {
        while ($filename = readdir($handlerDir)) {
            if ($filename != '.' && $filename != '..' && preg_match('/^plg_.+\.inc\.php$/', $filename)) {
                include_once $cd . '/include/user_include/plugins/' . $filename;
            }
        }
    }
+
+   $done = true;
}
 
/*
 * Load Plug-in Modules
 */
function include_plugin($mode)
{
    global $cd, $cfg, $plugin;
+   static $done;
+
+   if ($done) return;
+
    if ($handlerDir = @opendir($cd . '/include/user_include/plugins')) {
        while ($filename = readdir($handlerDir)) {
            if ($filename != '.' && $filename != '..' && preg_match('/^plg_.+\.inc\.php$/', $filename)) {
                include_once $cd . '/include/user_include/plugins/' . $filename;
            }
        }

SQL へのアクセスを減らす

 include/func_base.inc.php 
function db_connect() 
{
    global $dbname, $host, $user, $password;
+   static $link;
+
+   if (isset($link)) return $link;
+
    $link = @mysql_connect($host, $user, $password);
    if ($link && mysql_select_db($dbname)) {
        return $link;
    } else {
+       unset($link);
        if (file_exists('./SETUP/')) {
            $update_dir = '<p class="ref">Go to <a href="./SETUP/">SETUP</a> directory.</p>';
        } else {
            $update_dir = '<p>No SETUP directory found.</p>';
        }        
function init_config()
{
    global $config_table, $cd;
+   static $cfg;
+
+   if (isset($cfg)) return $cfg;
+
    $cfg = array();
    $sql = 'SELECT * FROM `' . $config_table . '`';
    $res = mysql_query($sql);
    if ($res) {
        while ($row = mysql_fetch_assoc($res)) {
            $cfg[$row['config_key']] = $row['config_value'];
        }
    } else {
+       unset($cfg);
        if (file_exists('./SETUP/')) {
            $update_dir = '<p class="ref">Go to <a href="./SETUP/">SETUP</a> directory.</p>';
        } else {
            $update_dir = '<p>No SETUP directory found.</p>';
        }
PHPがセーフモードの場合、mb_send_mail の additional_parameters が無効になるので、エラーとなる。この場合、./var/feedback/contents/feedback.inc.php の94行目を次のように変更する。（5つ目のパラメータを外すだけ） 
if (mb_send_mail($cfg['sendmail_address'], $subject, $message, $header, $param)) {
↓ 
if (mb_send_mail($cfg['sendmail_address'], $subject, $message, $header)) {
定量的な検証はしていないので、どの程度早くなるかは気持ちの問題が大きいような･･･。

「もっと読む」のリンク先を文書の続きに変更

function display_article_box($row)

                     '" rel="Bookmark">Permalink</a> ';

 画像などのバイナリファイルを「resources」フォルダにアップロードすると、FTPソフトなどで、そのファイルのダウンロードやパーミッションの変更が出来なくなる。 これは、アップロードされたファイルのパーミッションが「600」となるのが原因のよう。(うちのサーバーだけの問題かも？) files/include/func_files.inc.php 
function display_binary_box($row)
