| | troubleshoot slow loading visuals in Power BI (3rd Jul 25 at 9:56am UTC) | | Fixing slow load times for visuals in Power BI is mostly about locating bottlenecks in your data model, DAX measures, and visual configurations. This option allows you to see the individual time it took to query and the visual to render and refresh. It can help identify where and what is causing issues with rendering.
Once you've analyzed visuals and established where you are having problems, next evaluate your DAX measures to see if they are adding complexity. Complex DAX or nested functions can severely impact performance. Consider how to reduce calculations and depending on your performance metrics, limits. Evaluate using functions like SUMX and CALCULATE, those can add serious performance hits if there are excess calculations. Finally, make sure you are investigating the use of volatile functions like NOW() and RANKX() only when you must to be accurate.
Data model design is crucial as well. Make sure your model is a star schema and not snowflake schema. Review your column cardinality, and also remove any extraneous columns or convert high cardinality column (eg GUID) to simple unique keys. You can also leverage aggregations to pre-calculate values to improve speed.
Be protective of which visuals you put on a page. Use slicers judiciously. Avoid auto sizing visuals page or use of complex custom visuals unless necessary. For developers who want to hone their performance optimization skills, a tailored Power BI Course in Pune provides relevant study and real-life exercises as a part of providing the required user experience in development of reports.
