How to use element caching to speed up page loading

Reducing page load time can increase visitor retention and improve your SEO score. Site performance can be significantly improved by using element caching. When widgets are rendered on the server, the HTML output is stored in a database. This way, the next time the element appears, it will be pulled from the database instead of being re-rendered. This can significantly reduce server memory usage and first byte time for visitors (TTFB).

caveat

The element cache cannot be used to containdynamic labelingmaybeElements that display customized data(e.g. shortcode), such as a widget that displays the visitor's name. To ensure that element caching is used only when needed, this feature is deactivated by default. Activate caching only on static elements.

You may need to clear the element cache periodically for the following reasons:

• performance balancing: Maintain a balance between improved load times and up-to-date content by regularly refreshing the cache.
• Testing and Updates: Allows to test changes or updates on a website and see the results without waiting for the cache to clear naturally.

Clearing the cache is done at the site level, and the cache is cleared at the same interval for all elements.

Reduce server memory usage and first byte time by storing the widget's HTML output in the database and fetching it directly on the next load instead of re-rendering it (TTFB). Note, however, that element caching does not apply to widgets that contain dynamic tags or custom data.
