Docket Cache: WordPress Object Cache Accelerator

Docket Cache is a WordPress Object Cache Accelerator that supercharges your website using a persistent object cache, accelerates caching with the OPcache backend. It is an alternative to in-memory cache solutions and is intended to provide an alternative option for those who can’t use Redis or Memcached server.

Rather than using serialize and unserialize a PHP object to store into flat files, this plugin stores data by converting the object into plain PHP code which results in faster data retrieval and better performance with Zend OPcache enabled. It is compatible with most hosting providers and low-spec servers.

A friend who is a webmaster highly recommended this WordPress plugin to me. I have been using it for two months without any issues, and the results have been stunning. With the correct settings, my blog (not the site you are currently on) is much faster than before. In the past i used a Page Caching plugin, but I removed it because it caused some issues with the “freshness” of my posts (sometimes old data was served to visitors). The support and the reviews at WordPress.org are also excellent.

Docket Cache is open-source software, contributed and sponsored by individuals and organizations. You can also support the development of Docket Cache by making a one-off or recurring payment to sponsor the project.

Two suggestions:

1. Make sure you add some php memory to WordPress, so at least 128mb are available for the plugin. For example do no run WordPress with 128 mb, increase that to 256 mb or more if you have that option.

2. Using Docket cache can conflict with some plugin, so enable standard WordPress Debug to a Log for 24 hours. Use Dasboard Widget Suite plugin for easiness and Enable Debug widget. Remember to Disable or Remove Debug from your wp-config.php after you are done.
