What It Does

The Docket Cache is a persistent WordPress Object Cache solution designed to store data as plain PHP code. It offers an efficient alternative for users who are unable to utilize Redis or Memcached servers.

Unlike conventional approaches that rely on serializing and unserializing PHP objects to store them into flat files, this plugin transforms objects into plain PHP code. This method significantly enhances data retrieval speed and overall performance, especially when paired with Zend OPcache.

When it comes to reliable persistent Object Cache in WordPress, Redis or Memcached comes on top. However, those solutions require knowledge of server and rarely available at low cost or shared hosting servers.

The only viable solution is to store object caches in files. In WordPress, exporting PHP objects is not easy. Most plugins implementing file-based caching rely on serializing and unserializing objects to store and retrieve data.

Docket Cache takes a better approach by turning the object cache into plain PHP code. This solution is faster since WordPress can use the cache directly without running other operations.

Comparing to Alternatives

Docket Cache is a lightweight object cache plugin designed to improve site speed, especially on shared hosting environments. Compared to other popular object cache plugins, it offers simplicity and ease of use without requiring complex setups.

FAQ

Object caching stores database query results so they can be retrieved quickly the next time they are needed.

Cached data is served directly from the cache rather than making repeated database queries. This reduces the load on your server and makes your site faster.

In simple terms, object caching keeps frequently used data in a location where it can be accessed more quickly.

A RAM disk uses your server’s memory (RAM) to act as a storage drive. It can be a hardware device or a virtual disk.

Reading and writing data from RAM is much faster than from an SSD. Storing Docket Cache files on a RAM disk can greatly improve performance.

Please note that creating a RAM disk requires server administrator access (root), so this option is not available on shared hosting.

Here is an example command to create and use a RAM disk with Docket Cache:

$ cd wp-content/ $ sudo mount -t tmpfs -o size=500m tmpfs ./cache/docket-cache

To mount the cache path automatically when the server starts, update your /etc/fstab file.

For more information about RAM disks:

On Windows, create a RAM disk and set the DOCKET_CACHE_PATH to point to the RAM disk drive.
