It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress. ![](https://s.w.org/plugins/geopattern-icon/memcached-redux_98a1ab.svg) # Memcached Redux By [Scott Taylor](https://profiles.wordpress.org/wonderboymusic/) [Download](https://downloads.wordpress.org/plugin/memcached-redux.0.1.7.zip) * [Details](https://ewe.wordpress.org/plugins/memcached-redux/#description) * [Reviews](https://ewe.wordpress.org/plugins/memcached-redux/#reviews) * [Installation](https://ewe.wordpress.org/plugins/memcached-redux/#installation) * [Development](https://ewe.wordpress.org/plugins/memcached-redux/#developers) [Support](https://wordpress.org/support/plugin/memcached-redux/) ## Description Changes the famous Memcached WP Object Cache backend to actually use the Memcached class (not the Memcache class). Implements wp_cache_get_multi() and wp_cache_set_multi() ``` wp_cache_get_multi( array( array( 'key', 'group' ), array( 'key', '' ), array( 'key', 'group' ), 'key' ) ); wp_cache_set_multi( array( array( 'key', 'data', 'group' ), array( 'key', 'data' ) ) ); ``` Blog Post: [http://scotty-t.com/2012/06/05/memcached-redux/](http://scotty-t.com/2012/06/05/memcached-redux/) ## Installation 1. Install [memcached](http://danga.com/memcached) on at least one server. Note the connection info. The default is `127.0.0.1:11211`. 2. Install the [PECL memcached extension](http://pecl.php.net/package/memcached) 3. Copy object-cache.php to wp-content ## Reviews ![](https://secure.gravatar.com/avatar/bd2c05f81f1618d45ad4b7fc4fff0edaac0baac78a4f4f62c6ca35c9b09536ab? s=60&d=retro&r=g) ### 󠀁[Does its Job, fast – dangerous](https://wordpress.org/support/topic/does-its-job-fast-dangerous/)󠁿 [kech61](https://profiles.wordpress.org/kech61/) June 19, 2020 Well, the plugin does its Job (cloud/centos7/apache/php/fpm/7.3 + memcached) fine. However, my site is quite komplex (multilingual, bbpress, aso..). Yesterday I had to make some changes (new pages) and the menu-system completely fell apart. It was not possible to add menu items, the connect between language-versions fell appart– horrible. Issue was finally solved by renaming the object_cache.php in wp_contend. So: The performance is really fine, but admin have to know what they are doing and disable plugin when changing (at least) menues. ![](https://secure.gravatar.com/avatar/ed4bec46dd1607b9fcf368c5cd0c97efcac300b27e788a8cd333ec1dc9b4bdf0? s=60&d=retro&r=g) ### 󠀁[Simple but it works!](https://wordpress.org/support/topic/simple-but-it-works-9/)󠁿 [Olaf Lederer](https://profiles.wordpress.org/finalwebsites/) February 20, 2019 Using the object cache plugin on my VPS from Upcloud managed with Serverpilot.
