Perfect for WordPress site administrators, plugin and theme designers, developers
Fully translatable.
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);
}
}

Installation
- Upload the wptuner folder (inside the zip file) to your /wp-content/plugins/ directory
- Activate the plugin through the ‘Plugins’ menu in WordPress
- The plugin management page (Settings->WPtuner) provides settings, hints, and troubleshooting if the plugin will not fully auto-install.
Please report any install errors to me, at my site. It will help if you can copy the wpTuner Diagnostics produced when you set the WP Tuner Debug Level to 1.
Updating
- Deactive the existing plugin, to remove its hooks (in wp-config.php, etc)
- Copy the new files to replace the old (usually the plugins/wptuner folder)
- Activate the new plugin
FAQ

- Have you looked at the settings page (Settings->WP Tuner)? You’ll find installer error notes there. Most common: your WP root folder needs write permission (at least 0755), and WP Tuner must be able to set permissions on your
wp-config.phpfile to make it editable. - Are you logged in with Administrator permissions (level 10)? Normally, only admins see anything.
- If you continue to have trouble, please set the Debug Level to 1, copy the wpTuner Diagnostics and paste them into an error report at my site.

There’s little reason to bother changing the CSS. This is an admin-only tool; your readers will not see anything. However, there’s some CSS at the top of
wptunershow.php, and further down inwptunersetup.php.This is a fully translatable/localizable plugin. See the
wptuner.potfile, and the online gettext tools such as poedit. Please send me your translations; I’ll make them part of the distribution with credit to you! - How do I examine performance in more detail?

WP Tuner is an entire performance analysis toolkit. The built-in admin settings provide a set of default measures that can be enabled without manual intervention.
