PowerBI Super slow

Submitted by Anonymous on ‎10-19-2022 08:26 AM

Hi

PowerBI has become super super slow all of a sudden. In the past 2 weeks it has been impossible to check the gateways and datasources of each report for example. Also, when refreshing, it takes ages along with multiple fails. Either because the time has exceeded or because some source becomes undefined.

Is there any idea on how to fix this?

Thanks!

Hi @Anonymous ,

 

If your Power BI becomes slow, please consider following things:

 

Why are reports slow?

  • Insufficient capacity resources
  • Inefficient report designs
  • Dataset is slow, especially when reports have previously performed well
  • High concurrent report usage

 

Why are refreshes slow?

  • Insufficient CPU (refresh can be very CPU-intensive).
  • Insufficient memory, resulting in refresh pausing (which requires the refresh to start over when conditions are favorable to recommence).
  • Non-capacity reasons, including datasource system responsiveness, network latency, invalid permissions or gateway throughput.
  • Data volume - a good reason to configure incremental refresh, as discussed below.
