Title: APC Object Cache Backend Author: Mark Jaquith Published: 04.08.2010 Last modified: 04.05.2020 --- Шукати плагіни Цей плагін **не перевірявся з останніми 3-ма основними випусками WordPress**. Можливо, він більше не може розроблятися або підтримуватися, і він може мати проблеми сумісності при використанні з більш новими версіями WordPress. ![](https://s.w.org/plugins/geopattern-icon/apc.svg) # APC Object Cache Backend Від автора [Mark Jaquith](https://profiles.wordpress.org/markjaquith/) [Завантажити](https://downloads.wordpress.org/plugin/apc.2.0.7.zip) * [Деталі](https://uk.wordpress.org/plugins/apc/#description) * [Відгуки](https://uk.wordpress.org/plugins/apc/#reviews) * [Встановлення](https://uk.wordpress.org/plugins/apc/#installation) * [Розробка](https://uk.wordpress.org/plugins/apc/#developers) [Підтримка](https://wordpress.org/support/plugin/apc/) ## Опис 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. ## Встановлення 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! ## Часті питання 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). ## Відгуки ![](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/) 07.09.2017 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/) 03.09.2016 Easy to install.
