Purpose of Output Cache
- Using Output Cache settings, we can improve the page performance in SharePoint online.
- Faster page load and better user experience
- Page output cache settings can be configured at the site collection level, the site level, and for individual page layouts.
- It reduces the server control activities and calls to the database
