Efficiently managing query loads in Grafana dashboards can significantly reduce load times by minimizing the number of requests made to data sources. One effective method is to use the Dashboard data source feature, which allows sharing query results between panels, thus consolidating requests into fewer, more comprehensive queries. This approach is particularly beneficial when multiple panels visualize identical data, enabling users to potentially create complex dashboards that require only a single query per refresh. To implement this, a panel with a shareable query must first be created, after which other panels can use the Dashboard data source to access these results, streamlining the process and offering a performance boost.
