Optimizing report performance involves limiting the number of visuals per report page, simplifying complex DAX formulas, and avoiding nested calculations. Use measures rather than calculated columns for better performance. Implementing query folding in Power Query helps push data transformations to the source.
Power BI development should also optimize relationships and indexes in the data model and use Power BI’s performance analyzer to identify slow elements. Employing incremental refresh and aggregating large datasets are also key strategies. Monitoring and adjusting for efficiency as data volumes grow is essential for sustained performance.
