DreamPress includes built-in server caching, which speeds up your site significantly. Since caching creates static versions of your site, fewer resources are needed by the server when a customer visits your site. This allows your site to not only load faster but also helps manage larger amounts of traffic. However, when caching is not working, your site will typically run slower, and your resource usage will increase.
Do I need a caching plugin?
DreamPress sites can access two server caching options:
- Nginx Helper Plugin
- Redis Cache (DreamPress Pro only).
Many guides recommend caching plugins such as WP Super Cache on WordPress sites. However, since DreamPress comes with built-in caching, third-party caching plugins are not necessary and could even conflict with the built-in DreamPress cache.
Redis Object Cache
DreamPress Pro plans also have access to Redis Object Cache, which stores WordPress objects in memory. For more information on Redis Object Cache, see the following article:
When would I need to purge my cache?
When you make changes to your site, such as customizing or creating new content, the new changes may not show live because your site's old version is cached. Purging your cache can help to push your changes live so visitors see the most recent version of your site.
