PowerBi Desktop Performance Issues

Hi bhalicki 

Power BI Desktop has felt a lot heavier for me and my team lately, especially after the recent updates. It’s frustrating when you’ve got a good machine and it’s still crawling! Here’s my “battle-tested” list of fixes and tips that have actually made a difference for us:

1. Check the “Enhanced Metadata” setting: Go to Options > Preview features and turn OFF anything related to enhanced metadata. This one setting alone has rescued a few of my .pbix files from lag city.

2. Trim your data as early as possible: In Power Query, do your filtering and column reduction at the very first step. Less data in = less RAM and faster everything.

3. Try switching to SQL authentication: If you’re on Windows Auth and things are slow to connect, test SQL Auth as a quick experiment. Sometimes it’s just an odd domain delay or Kerberos weirdness.

4. Shut down other resource hogs: Sounds obvious, but close Teams, Outlook, Chrome tabs, and anything else chewing up memory.

5. Use Performance Analyzer: Turn this on (under the View tab) and see if it’s a particular visual or query that’s slow. Sometimes it’s just one measure or step bogging everything down.

6. Try the previous Power BI version: Download last month’s Power BI Desktop and open your report there. If it’s noticeably faster, you might have hit a bug in the latest update worth reporting.

7. Clear out temp Power BI folders: Delete everything inside C:\Users\[YourUser]\AppData\Local\Microsoft\Power BI Desktop\AnalysisServicesWorkspaces and restart Power BI Desktop.

This version of Power BI is a bit temperamental, but these steps have helped me squeeze decent performance out of it. If all else fails, shout here and I can help dig in deeper (happy to look at a sample PBIX if you want!).
