/**
 * Plugin Name: Performance Lab Server Timing Object Cache Drop-In
 * Plugin URI: https://github.com/WordPress/performance
 * Description: Performance Lab drop-in to register Server-Timing metrics early. This is not a real object cache drop-in and will not override other actual object cache drop-ins.
 * Version: 3
 * Author: WordPress Performance Team
 * Author URI: https://make.wordpress.org/performance/
 * License: GPLv2 or later
 * License URI: https://www.gnu.org/licenses/old-licenses/gpl-2.0.html
 *
 * Object cache drop-in from Performance Lab plugin.
 *
 * This drop-in is used, admittedly as a hack, to be able to measure server
 * timings in WordPress as early as possible. Once a plugin is loaded, it is
 * too late to capture several critical events.
 *
 * This file respects any real object cache implementation the site may already
 * be using, and it is implemented in a way that there is no risk for breakage.
 *
 * If you do not want the Performance Lab plugin to place this file and thus be
 * limited to server timings only from after plugins are loaded, you can remove
 * this file and set the following constant (e.g. in wp-config.php):
 *
 *     define( 'PERFLAB_DISABLE_OBJECT_CACHE_DROPIN', true );
 *
 * @package performance-lab
 * @since 1.8.0
