Object Cache 4 everyone


Improve your server performance using Memcached for object caching or improve your server performance using disk support for object caching.

Less resources needed and better pagespeed.

Less database queries needed.

Detects automatically any Memcached server running and adds an object-cache.php file to your WordPress site.

Default memcached servers tested:
— Any SiteGround Memcached setup

Since 1.4, you can declare your own Memcached Server instance in the wp-config.php file.

Starting from version 1.6, you have the option to declare in the wp-config.php file whether you want to use the external disk object cache in case the Memcached Server is not present.
Outdated or malfunctioning disks can negatively impact website performance.

This plugin includes a modified template from this project:
A WordPress object cache that uses the memcached (not memcache) PECL extension.

This is a really good one. There are a surprisingly few number of plugins devoted solely to object caching, so I was pleased to find this little gem. Thanks to the developer for it, and please keep it updated and supported! It fills an important need. It is lean and simple to use without having a bewildering number of options that make things easy to break.
I installed and its working very well at the moment, I will do some test but at this moment is working great.
Works better than LiteSpeed Cache With the Litespeed cache plugin → Database Query 100+ With this plugin → Database Query 50+
Sure, I looked at the "it made my site 2x slower" post, but the other 5 star reviews tells a better story. This plugin absolutely works, and it also drastically reduced the MySQL CPU. The default of 64MB is too small, I gave memcached 256M and so far, so good.
