WordPress + Memcached = Awesome

If you’re already running memcached and using WordPress, you can provide an object cache directive to help speed things up. All you need to do is place this object-cache.php script in the /wp-content directory (not the plugins folder). Then add the following to the wp-config.php:

/** Memcached Support */
global $memcached_servers;
$memcached_servers = array('default' => array('127.0.0.1:11211'));

If memcached is running on another port besides 11211, make sure to change the port value in the memcached_servers line. You can verify that caching is taking place by tailing the memcached log:

$ tail -f /var/log/memcached.log

You should see some pretty verbose output in the log. For the more documentation, check out the SVN branch.
