Title: APC Object Cache Backend Author: Mark Jaquith Published: 4. August 2010 Last modified: 4. Mai 2020 --- Plugins durchsuchen Dieses Plugin **ist nicht mit den jüngsten 3 Hauptversionen von WordPress** getestet worden. Es wird möglicherweise nicht mehr gewartet oder unterstützt und kann Kompatibilitätsprobleme haben, wenn es mit neueren Versionen von WordPress verwendet wird. ![](https://s.w.org/plugins/geopattern-icon/apc.svg) # APC Object Cache Backend Von [Mark Jaquith](https://profiles.wordpress.org/markjaquith/) [Herunterladen](https://downloads.wordpress.org/plugin/apc.2.0.7.zip) * [Details](https://de-at.wordpress.org/plugins/apc/#description) * [Rezensionen](https://de-at.wordpress.org/plugins/apc/#reviews) * [Installation](https://de-at.wordpress.org/plugins/apc/#installation) * [Entwicklung](https://de-at.wordpress.org/plugins/apc/#developers) [Support](https://wordpress.org/support/plugin/apc/) ## Beschreibung APC Object Cache provides a persistent memory-based backend for the WordPress object cache. 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. ## Installation 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! ## FAQ 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). ## Rezensionen ![](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. September 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. September 2016 Easy to install. Boost website (APC totally eliminates the time of retrieving the file from disk and the time spent compiling). ![](https://secure.gravatar.com/avatar/97bbe4fe76251bd8de789468d4e055a2a38da2615beb64caba53e5aff6c24084? s=60&d=retro&r=g) ### 󠀁[Excelente Five Stars- Extra Performance](https://wordpress.org/support/topic/excelente-five-stars-extra-performance-2/)󠁿 [General Seed](https://profiles.wordpress.org/autocultivo/) 7.
