Memcached Object Cache provides a persistent backend for the WordPress object cache. A memcached server and either the 
the PECL Memcached or PECL Memcache extension and class are required. Detects either the PECL Memecache or PECL 
Memcached (Memcached preferred) class and uses the appropriate interface. That means you don’t need to figure out 
which PHP class is available in your installation, the plugin will detect the proper configuration.
This plugin does not require manual copying of files between directories for installation, and it doesn’t require the installer 
to differentiate between the memcache and memcached PECL extensions if they know their host makes once available.
Also, because this plugin autodetects the PECL extension available, for those that develop on Windows where the 
PECL Memcached extension is not generally available, you can maintain a common configuration with your Linux host 
where that extension is common.
Plugin creates a dashboard menu option under “Tools” where you can view your memcached statistics.
Plugin is based laregly on previous works by Matt Martz, Ryan Boren (https://wordpress.org/plugins/memcached/) and 
Scott Taylor, Ryan Boren, Matt Martz, Mike Schroder ( https://wordpress.org/plugins/memcached-redux/ )
