How do Power BI developers optimize report performance?
Power BI developers optimize report performance by minimizing the complexity of data models, avoiding large datasets where unnecessary, and reducing the number of calculated columns. Efficient DAX expressions and filtering help improve query performance. Power BI developers also use data aggregations and optimize visuals by limiting the number of elements rendered on dashboards. Utilizing proper indexing, simplifying data refresh rates, and choosing appropriate visuals for large datasets contribute to faster, more efficient reports. Overall, performance tuning ensures dashboards remain responsive even with extensive data.
