How can the performance of Power BI dashboards be improved?

Performance of Power BI dashboards may be improved by reducing the amount of images and intricate computations on each page. Load times are decreased by using efficient data models with suitable aggregations and indexing. Performance can also be improved by following recommended practices when writing in DAX (Data Analysis Expressions), such as eliminating needless nested functions. Furthermore, by utilizing incremental data refreshes, processing time is decreased since only fresh data is loaded. Regularly tracking and evaluating performance indicators facilitates the identification of bottlenecks and ongoing dashboard optimization.

To improve the performance of Power BI dashboards, consider the following strategies:

1. Optimize Data Model: Use star or snowflake schemas and eliminate unnecessary columns or tables. This reduces the load on Power BI when processing data.

2. Use Aggregations: Implement aggregations for large datasets to summarize data before bringing it into the dashboard. This reduces query complexity.

3. Limit Visualizations: Avoid overloading a dashboard with too many visuals, as each visual queries the data model independently. Fewer visuals improve load times.

4. Efficient Querying: Leverage query folding, which pushes data transformations back to the data source, minimizing the processing done by Power BI.

5. Optimize DAX: Write efficient DAX formulas, avoiding complex calculations and filters that can slow down dashboard rendering.

6. Use Incremental Refresh: When working with large datasets, use incremental refresh to load only the data that has changed instead of the entire dataset.

7. Reduce Data Imports: Whenever possible, filter data at the source to import only relevant records into Power BI.
