Alternative PHP Cache
This module integrates the APCu PHP extension for in-memory caching. It's best used for cache data that doesn't change often and remains relatively small, leveraging APCu's efficient key-value storage to improve site performance.
Warning message
Do not use development versions in production sites. They are thought to be used to help with the development of the module.
The APC User Cache (APCu) extension is an in-memory key-value store for PHP. Its goal is to provide a free, open, and robust framework for in-memory caching.
This module integrates the APCu extension in Drupal.
Use the cache implemented by this module for caches that do not change often and will not grow too big to avoid fragmentation. The default setting of APCu will allow you to store 32 MiB. Make sure you tweak this according to your website's needs. An example configuration could be to cache cache and cache_bootstrap in APCu, cache_field and cache_menu in Memcached, and store cache_filter in the database.
