There are several caching plugins you can use for your WordPress sites, which can help to improve your website load time and overall performance. They can also help your site to handle large spikes in traffic like the Slashdot effect. The following is a general overview of recommended plugins you can use on DreamHost's servers:
Enabling Page Caching in the panel
This option is not available (or necessary) for DreamPress installations since DreamPress uses its own built-in server cache.
WordPress sites are able to activate Page Caching in the panel, which activates the Simple Caching plugin.
- Navigate to the Manage Websites page.
- Click the Manage button to open the Domain Settings page, which allows you to adjust various settings for your site.
- Click the Website tab.
- Scroll down to the WordPress section.
- To the right of Page Caching, enable the toggle.
- A checkmark displays when active.
WP Super Cache
WP Super Cache creates a static file cache of your site and loads that instead of using PHP to generate the page. Picking up where WP-Cache left off, this plugin includes advanced features as well as a plugin and hooks system. WP Super Cache is already included and activated with all new WordPress Deluxe installs from the DreamHost web panel. If you're on Shared Hosting, this is the best option.

The Docket Cache plugin
The Docket Cache — Object Cache Accelerator plugin is a filesystem-level Object Cache used as an alternative to services like Redis or Memcache. It stores data by converting PHP objects into plain PHP code, which helps to improve performance.

DreamPress uses a built-in server cache along with pre-installed plugins that are specifically configured to help WordPress take full advantage of these features. There is no need for DreamPress users to install any caching plugins.
