[jpquesada]

Since December 2024, Power BI has become very slow. Is anyone else experiencing this problem?

Hi  @jpquesada 
Thank you for reaching out on the Microsoft Fabric Community Forum!

Here are some steps to help improve Power BI Service performance:

• Check that your data sources are responsive. Consider reducing the frequency of data refreshes. Avoid overusing Direct Query, as it can slow down performance.
• Limit the amount of data you're importing by filtering or summarizing. Optimize your DAX queries and avoid overly complex calculations. Remove any unused columns and tables to reduce unnecessary data. Clear your browser cache or try using a different browser if needed.
• If needed, upgrading to Power BI Premium will provide dedicated capacity for better performance. Use the Power BI Admin portal to monitor resource utilization.
• Use query Diagnostics and the Performance Analyzer to identify slow queries. Implement aggregations for large datasets to speed up reports. Limit the number of visuals per report and avoid using high-cardinality fields or complex chart types. Use bookmarks to show only a subset of data at a time, which can improve report load times.

If the issue persists even after trying these steps, please consider raising a support ticket for further help.

Hi @jpquesada 

Some users have reported slower Power BI performance since December 2024. Possible causes include:

1. Service Performance Issues: Microsoft may be facing service disruptions.
2. New Updates/Features: Recent changes could impact performance.
3. Large Data Models: Bigger or more complex data models can slow down performance.
4. Data Source Issues: Problems with slow or large external data sources.
5. Gateway Problems: Performance issues with the on-premises data gateway.

To address this, try clearing the cache, optimizing queries, checking refresh schedules, or testing connectivity to data sources. If the issue persists, check Microsoft's Power BI service status or contact support.
