What is the role of performance optimization in Power BI consulting services?

Performance optimization ensures that Power BI solutions function smoothly, even with large datasets or complex reports. Consultants optimize data models by reducing the number of columns, using aggregations, and simplifying relationships. DAX queries are refined for efficiency, and visuals are minimized to reduce rendering time. Incremental data refresh is configured to update only new data, saving resources. Testing is performed to evaluate loading times and interactivity. By focusing on performance optimization, Power BI consulting services ensure that the Power BI solution delivers fast, reliable insights without hindering user experience, enabling efficient decision-making.
