A Closer Look at Lazy Loading Grafana Dashboards
Lazy loading of dashboard panels has been a popular feature request from the Grafana community for many years, and it was finally added in v6.2. In previous versions, the moment you opened a dashboard Grafana will issue queries for every panel, even those you have to scroll to see. This can create high peaks in load to your data source backends. Meanwhile, you may never actually scroll down to look at all of those panels, so executing queries for those panels would have been pointless.
