CPU Utilization after open any report

Hi Tishchenko,

The CPU spike you're seeing when opening Power BI reports is concerning. Here are some things to investigate:

Common causes:

1. Complex visuals loading - Multiple visuals with heavy calculations all refreshing at once
2. Large datasets - Initial data load into browser memory
3. Custom visuals - Some custom visuals (especially older ones) can be CPU-intensive
4. DAX measures - Complex measures calculating across all visuals on page load
5. Browser issues - Outdated browser, too many extensions, or insufficient resources

Troubleshooting steps:

• Use Performance Analyzer in Power BI Desktop to identify which visuals are slow
• Check if specific reports cause this or all reports

Best regards!

Hi Tishchenko,
Optimize your report as much as you can. Use external tools like Measure Killer to remove unwanted columns and measures. Use Performance analyzer and optimize your DAX as much as you can wherever required.
