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/ )

Simple Cache was constructed after getting frustrated with the major caching plugins available and building sites with developer-only complex caching solutions that get millions of page views per day. Simple Cache promises the following:
<ul>
<li>Extremely simple one-click install. There is an on-off switch. That’s it. No need to wade through 50 complicated settings.</li>
<li>Simple Cache makes your site run very fast so you can handle lots of traffic.</li>
<li>Extremely easy to delete. Don’t like the plugin? You can remove it, and your website won’t break.</li>
<li>Easily clear the cache if you need to.</li>
<li>Enable gzip compression</li>
<li>Want to get advanced with object caching (Memached or Redis)? An advanced mode is available that will automatically setup <a href="https://wordpress.org/plugins/batcache/" rel="ugc">Batcache</a> and <a href="https://wordpress.org/plugins/memcached/" rel="ugc">Memcached</a>/<a href="https://wordpress.org/plugins/wp-redis/" rel="ugc">Redis</a> for you.</li>
</ul>
If you need your site to run fast, don’t have time to mess with complicated settings, and have been frustrated by other caching plugins, give Simple Cache a try.

Simple Cache

I had this plugin on about 30 sites two years ago, but have since removed it, one by one, because of bad experiences of many kinds. The last was removed today, after site crashed due to fatal error in caused by the last update to this plugin.

When deactivating it also puts DEFINE('WP_ACHE', false); at the top of wp-config.php. This is bad and makes trouble using another cache plugin, unless this line is manually removed.

I can not recommend this plugin. Be aware of the thing mentioned above, when uninstalling to try out another.

Sorry - bad plugin

A very simple plugin to make your site run lightning fast with caching.
