Developers can improve
Power BI development report performance by optimizing visuals and reducing the number of calculations that run at query time. Limit the number of visuals on a report and remove unused or redundant visuals. Reduce complex DAX expressions and avoid inefficient calculations like using filters within measures. Instead, pre-aggregate data in the model. Enable query reduction techniques such as disabling cross-highlighting and setting the data import mode to DirectQuery or Aggregations for large datasets. Monitoring with Performance Analyzer and tweaking dataset refresh settings also helps boost report responsiveness.
