From the developer
Nawawi Jamili's own description of Docket Cache, lightly tidied.
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.
Why use this plugin?
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 object caches in files. In WordPress, exporting PHP objects is not straightforward. Most file-based caching plugins rely on serialising and unserialising objects to store and retrieve data.
Docket Cache takes a better approach by turning the object cache into plain PHP code. This is faster because WordPress can use the cache directly without additional processing.
