The closer they are to the source, the faster they are likely to perform. Where possible, push calculated columns and measures to the source. Limit complex measures and aggregations in data modelsĬreate calculated measures instead of calculated columns.If a custom visual performs poorly, consider replacing it with a different visual. Uncertified custom visuals are generally not tested by the Power BI team. Test custom visual performance before useĬustom visuals can perform poorly when handling large datasets or complex aggregations.If you use the same gateway for a scheduled refresh and a live connection, live connection performance will slow down during the scheduled refresh. Use separate gateways for Power BI service live connection and scheduled data refresh.On-premises data gateway (also known as Enterprise Gateway) imports nothing, which is more efficient when working with large databases. Personal Gateway imports data into Power BI. Use on-premises data gateway instead of Personal Gateway.By disabling unnecessary interactions, you reduce the number of queries fired at the back end, which improves report performance. Remove unnecessary interactions between visualsīy default, all visuals on a report page can interact with one another.In general, limit pages 30 points, assuming each type of visual is worth a different number of points: Limit widget visuals to eight per report page and grids to one per page. Using too many visuals on a single report slows report performance. Limit the number of visuals in dashboards and reports.By using Power BI data sensitivity labels, you raise user awareness about security and how reports should be shared inside and outside the organization.
Low Business Impact (LBI) and Medium Business Impact (MBI) data do not require exceptions. High Business Impact (HBI) data requires users to request a policy exception to share the data externally. Use Power BI sensitivity labels to classify data as high, medium, or low business impact. Categorize report data by business impact.
Certified custom visuals are the only custom visuals that can be viewed in Export to PowerPoint mode and email subscriptions. Microsoft verifies that certified custom visuals have robust, high-performance code.
Power BI certified visuals are custom visuals on AppSource that have passed rigorous quality testing. With RLS, Power BI only imports data the user is authorized to view. Row-Level Security restricts user access to certain rows in a database depending on the characteristics (role) of the user executing a query.
