The new caching plugin, introduced in V7.9, drastically reduces the loading times of a site. It compiles the code significantly faster, thus allowing pictures to load quicker. For more info go to the Lazy Load section.
The caching plugin, exclusively designed for routes and queries, comes with three possible options. From the Caching menu (Settings -> Site Settings -> Caching), admins can use the Caching Engine to do the following:
(Caching Engine) Off
Disables the caching engine. Metadata caching will still be enabled, using the Files adapter.
(Caching Engine) Files
Uses static files for caching (recommended).
(Caching Engine) Table
Uses the database for caching (slower than the Files adapter).
