If a dashboard references a large number of data sources or records and is taking longer than 20 seconds to load, a pop-up notification may ask if you want to cache the dashboard. Caching a dashboard can significantly improve load times but the data will no longer be live; instead, it will display the state of the data at the time the dashboard was cached. Caching a dashboard will also cache it for other professional users who load the dashboard for the same group.
Data is refreshed overnight or it can be refreshed manually by selecting Update cached data above the dashboard. If a cached dashboard is not viewed for more than seven days, the system will stop automatically updating the cache overnight but the configuration will still be saved. The next time the dashboard is loaded, it will update all data.
Caching is enabled in the builder interface, so it may not be available for all large dashboards.
You can also manually turn off caching by selecting the information icon in the top right corner of the dashboard and unchecking the box next to Cache this dashboard. This will turn off the cache for everyone with access to this dashboard. Note that this check box will only appear if the dashboard has previously taken more than 20 seconds to load or it has been previously cached.
