What is the Docket cache?

The Docket cache is a persistent WordPress Object Cache that is stored as a plain PHP code. Intends to provide an alternative option for those who can't use Redis or Memcached server.

How does Docket Cache store data?

Docket Cache stores data by converting the object into plain PHP code, resulting in faster data retrieval and better performance with Zend OPcache enabled.

Why use Docket Cache?

Docket Cache provides a better approach to object caching by turning the object cache into plain PHP code, allowing WordPress to use the cache directly without running other operations.

What are the requirements for using Docket Cache?

To use Docket Cache, you need PHP 7.2.5, WordPress 5.4, and Zend OPcache.

Where can I find the documentation for Docket Cache?

Incredible plugin, lovely documentation, helpful support forum

By trendycloud on October 22, 2024

Hello from France!

I only discovered your plugin two weeks ago.

Usually I use Redis for all websites hosted on a VPS.

However, Docket Cache rocks on (fast) shared hosting.

Documentation is a delight: useful and detailed.

I really loved that each option had a constant to configure it.

And reading/searching the support forum really helped me.

Long story short: I will deploy this plugin whenever it is possible.

Have a great day! :)

Excellent Cache Product

By garthvs on January 8, 2024

This is the first cache that simply works with dynamic pages. My Pagespeed scores increased significantly. Other caches work but not on dynamic websites.

Good but not compatible with translatepress

By unicalus on October 10, 2023

Very good if You not using Translate press. With translate press sometimes all menu linking to wrong language and I need always clear cache...

It Just Works!

By mastiyok on September 29, 2023

I've been struggling finding plugin for simple and working object caching plugin when I found this plugin. I installed it and It just made my day! It fantastically works!

Really Great

By an0nbr on September 26, 2023

This plugin is really good

If you are trying to make memcached work

By alonelypath on September 1, 2023

Do not forget to download the droplet and to copy into your ~/wp-content/. Works great !

I would give 10 stars if a could

By dimal (dimalifragis) on August 30, 2023

I can't believe how good this plugin really is, especially if you are using a limited hosting plan. I was not able to use Page caching plugin because of Wordfence is not compatible with any of them (despite the fact that everybody is using those together).

Docket cache was the solution for me. Gave a significant boost ....

Goof for object cache accelerator

By zepolo on July 19, 2023

Great alternative to Redis and Memcached.

The documentation and some of the question marks could contain a little more information for me too (tips for optimum settings for example).

Great and quicky support

Great plugin and great support

By ms100 on April 30, 2023

Great alternative to Redis and Memcached for shared hosting servers. Really happy with this plugin.

The documentation and some of the question marks could contain a little more information for me to understand everything better, being a beginner at webdeveloppement. But that is a minor detail.

Personally I would not set the Trash Bin to cleanup by default. Because maybe one plugin-user will not check that setting, and then later find out something has been removed permanently.

However, thanks for sharing this plugin and providing amazing support.

I would definately advise my friends to use the Docket Cache plugin!

Very good plugin. Site back-end feels snappier. Good job here!

By Mark (markob17) on March 29, 2023

Using Redis on my VPS and it makes things a lot faster, especially when in the back-end of Wordpress. My friend is on shared hosting and can't install redis, so I installed this instead. Using Query Monitor plugin, Docket Cache cuts the queries down just as much as Redis does on my server. Quite impressed. Thank you for this. Good stuff!
