Which method should you use to determine query timings for a report page visual?

To determine query timings for a report page visual, utilizing the Performance Analyzer is the most effective method. The Performance Analyzer is specifically designed to help Power BI users understand how long each visual takes to render, along with the duration of any underlying queries that are executed to fetch data for those visuals.

When you initiate the Performance Analyzer, it provides detailed insights into the performance metrics, enabling you to see which visuals may be causing delays and how long data retrieval is taking. This is particularly beneficial when optimizing reports, as it allows you to identify bottlenecks and refine visuals based on their performance data.

While other methods, such as refreshing the data model or running the Best Practices Analyzer, are useful in different contexts (like ensuring data is current or checking report design adherence), they do not focus specifically on the timings related to report page visuals. Session Diagnostics from the Power Query Editor is more centered around transforming and loading data rather than measuring the performance of visual rendering on report pages.

Using the Performance Analyzer will provide the precise and relevant information needed to assess and improve the efficiency of your report visuals.
