Docket Cache is a persistent WordPress Object Cache that stores cached data as plain PHP code. It is designed as an alternative for sites that do not have access to Redis or Memcached.
Most file-based caching plugins use serializing and unserializing to save PHP objects to flat files. Docket Cache takes a different approach by converting objects into plain PHP code. This makes data retrieval faster and improves overall performance, especially when Zend OPcache is enabled.
For more information, please refer to the documentation on Caching In WordPress.
For reliable persistent Object Cache in WordPress, Redis or Memcached are the top choices. However, they require server knowledge and are rarely available on low-cost or shared hosting plans.
The alternative is to store…
After installing this plugin I saw significant speed increases on page loading times. I’ve used it in combination with other page and browser cache plugins and have had no conflicts.
My website simply lost the drag and slowness… wow!
After uninstall this plugin left a tons of files around in wp-content folder.
Docket Cache hat meine Seiten mit Elementor Pro, LearnPress und PMP deutlich schneller gemacht. Die Datenbankzeit ging praktisch auf null, die Anzahl der Queries wurde stark reduziert, und das Backend fühlt sich viel reaktionsschneller an. Einfach zu installieren, leicht zu konfigurieren und perfekt kompatibel mit WP Rocket und WP Optimize. Absolute Empfehlung!
Works flawless, really simple way to test object cache locally when developing, without needing to setup memchache or redis or similar.
