P_BLOG本体の改造

負荷軽減

Plug-in 読込み処理を1回だけに

include/func_base.inc.php

/*
 * 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;
            }
        }
    }
+
+   $done = true;
}

SQL へのアクセスを減らす

include/func_base.inc.php

/**
 * MySQL Connection
 */
function db_connect() 
{
    global $dbname, $host, $user, $password;
+   static $link = FALSE;
+
+   if ($link) return $link;
+
    $link = @mysql_connect($host, $user, $password);
    if ($link && mysql_select_db($dbname)) {
        return $link;
    } else {
+       $link = FALSE;
        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>';
        }        
//================================================================
// CONFIG
//================================================================

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>';
        }        

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・・・。
