How to Troubleshoot Performance Issues in Power BI Reports?

To troubleshoot performance issues in Power BI reports, start by analyzing query performance using Performance Analyzer. Optimize data models by reducing column cardinality and removing unnecessary fields. Use measures instead of calculated columns when possible. Limit visuals on report pages and avoid complex DAX expressions. Ensure relationships are properly indexed and leverage star schema design. Review data refresh times and reduce imported data volume. Utilize tools like DAX Studio and VertiPaq Analyzer for deeper diagnostics. Enrolling in a Power BI course can provide hands-on skills to better manage report efficiency and troubleshoot issues effectively for optimal performance.
