APC must be available on your PHP install. An object cache is a place for WordPress and WordPress extensions to store the results of complex operations. On subsequent loads, this data can be fetched from the cache, which will be must faster than dynamically generating it on every page load. The APC Object Cache backend is also compatible with [Batcache](https://wordpress.org/extend/plugins/batcache/), the powerful full page caching engine that runs on WordPress.com Be sure to read the installation instructions, as this is **not** a traditional plugin, and needs to be installed in a specific location. ## Instalacija 1. Verify that you have PHP 5.2.4+ and a compatible APC version installed. 2. Copy `object-cache.php` to your WordPress content directory (`wp-content/` by default). 3. Done! ## HSP Does this work as a backend for Batcache? Yes! APC 3.1.1+ supports incrementers and handles its own cleanup of expired objects, so it works just fine for Batcache. Lower versions of APC will work, but the hits trigger will be disabled. Does this support versions of WordPress earlier than 3.3? Maybe, but I’m not going to support them, and you shouldn’t still be running them! I share `wp-config.php` among multiple WordPress installs. How can I guarantee key uniqueness? Define `WP_APC_KEY_SALT` to something that is unique for each install (like an md5 of the MySQL host, database, and table prefix). ## Pohódnoćenja ![](https://secure.gravatar.com/avatar/85f1e397187c7681514f0f4b99c8aa6e022b062b24575cbdc10652e02d82caa2? s=60&d=retro&r=g) ### 󠀁[Very good](https://wordpress.org/support/topic/very-good-2530/)󠁿 [Grzegorz.Janoszka](https://profiles.wordpress.org/grzegorzjanoszka/) 7. septembra 2017 It reduces the number of sql queries by about half and thus reduces the server load. Highly recommended if you have the correct PHP APC modules. ![](https://secure.gravatar.com/avatar/f3fbec49f0e9d50e5ea6258a9f7c79253ae512019efa10d7565b5737594f3376? s=60&d=retro&r=g) ### 󠀁[greatly speed up WordPress](https://wordpress.org/support/topic/greatly-speed-up-wordpress/)󠁿 [Vinyl Roads](https://profiles.wordpress.org/vinyl-roads/) 3. septembra 2016 Easy to install.
