WP Tuner

Description

The (mu-compatible) WP Tuner plugin for WordPress is a powerful and easy to use way to answer many hard questions about why your blog is slow or cranky. What’s causing the slowdown? Is it a plugin? Is it your host?

Used with a bit of common sense, this powerful plugin will help blog administrators as well as software developers improve their WordPress blog performance.

Perfect for WordPress site administrators, plugin and theme designers, developers

Advanced Use

Here are more advanced ways to make use of WP Tuner. Please share your questions and/or stories examples to share with others!

1) Hook any WordPress action

In wptuner.php, you will find a default set of action hooks. You can add as many hooks as you like for other actions. They look like this (just change “admin_footer” to the name of the action you want to measure):

add_action('admin_footer', 'wpTuneFilterTime' );

Each hook adds a line to the WP Tuner performance analysis table, when that action is triggered.

2) Time anything at all in WordPress

WP Tuner contains a function that causes performance analysis for any section of WordPress code. Just use
wpTuneMarkTime(‘My Marker string’);

…at the beginning of the code you want analyzed. Add another marker at the end if needed.

For example, suppose you want to know how much time is spent loading each of the plugins you have enabled. Here’s how to do it, by adding two simple lines to wp-settings.php:

if (function_exists(wpTuneMarkTime)) wpTuneMarkTime('Load Plugins'); // ** Add THIS line **

if ( get_option('active_plugins') ) {
  $current_plugins = get_option('active_plugins');
  if ( is_array($current_plugins) ) {
    foreach ($current_plugins as $plugin) {
      if (function_exists(wpTuneMarkTime)) wpTuneMarkTime('Plugin: '.$plugin); // ** Add THIS line **
      if ( '' != $plugin && 0 == validate_file($plugin) && file_exists(WP_PLUGIN_DIR . '/' . $plugin) )
        include_once(WP_PLUGIN_DIR . '/' . $plugin);
    }
  }
