If you are experiencing delays in loading your Power BI “publish to web” reports, the following actionable suggestions can help mitigate the delays;
1. Refine the Data Model.
To begin with, you will need to compact your data model. Remove unused columns, tables, or figures that do not contribute to the report. This, in turn, helps speed up the load time by reducing the processing of the data.
2. Avoid Deep Nesting Generally Complex Formulas
DAX calculations or any other large measures should also be avoided as much as possible because they are always done in real-time. Where possible, always pre-aggregate the data instead. This is because Power BI will not need to carry out complex calculations on its database when generating the report.
3. Cut Back on the Use of Overly Complicated Charts or Graphics
A large number of visuals or complicated visuals, such as those with many data points, can reduce report performance. It is advisable to reduce the number of pages with several visuals or ease the types of visuals being used.
4. Opt for Data Import Mode rather than DirectQuery
Do not rely solely on the DirectQuery option (which always queries the source) for real-time data. Go to import mode that is, into the application and into Power BI, which makes it much faster to load the reports.
5. Evaluate Performance with the Performance Analyzer of Power BI
In addition, the application comes with a Performance Analyzer tool that helps you see where the problem is with the report performance. Leverage this to resolve any issues that may delay performance.
Applying these measures can help in improving the loading speed of your reports published on the web through Power BI.
