Use progressive caching
If Progressive Caching is enabled (not available after Kentico Xperience version 11), the system optimizes access to uncached data so that concurrent threads only use a single data access operation and share the results. This leads to better performance if the website is under a heavy load, without the drawback of not having the latest data available.
Verifying The Check
To determine whether progressive caching is enabled on your portal site you can navigate to the Settings Application and then find the System > Performance settings.
From there you will want to find the Server Content Caching section and ensure that Use progressive caching is enabled.
Progressive caching in MVC live sites must be implemented via custom code. For more information on this please visit the Caching In Custom Code portion of the Kentico Xperience documentation or reach out to the Toolkit For Kentico team.
Changes to your site should only be made by an experienced Kentico Xperience developer. If you need assistance in making these changes please reach out to the Toolkit For Kentico team to be connected with a Kentico Xperience partner.
