Hi Anonymous ,

 

You can find the changes of Power BI Desktop latest version from the document What's new in the latest Power BI Desktop update?.

 

When the refresh is in fact slow or crash, it can be due to several reasons:

  • 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 data source system responsiveness, network latency, invalid permissions or gateway throughput. You may increase the capacity for workspaces to increase the model refresh parallelism frequency.
  • Data volume - a good reason to configure incremental refresh, Incremental refresh can significantly reduce data refresh duration, especially for large model tables. See more: Incremental refresh in Power BI Premium .

 

See more details: https://docs.microsoft.com/en-us/power-bi/whitepaper-powerbi-premium-deployment#why-are-refreshes-slow.

 

You can also use some tips to improve the performance:

 

   Enable Row-Level Security (RLS) where applicable.

   Use Microsoft AppSource certified custom visuals where applicable.

   Do not use hierarchical filters.

   Provide data categorization for Power BI reports (HBI, MBI, LBI).

   Use the On-premises data gateway instead of Personal Gateway.

   Use slicers sparingly.

   Remove unused tables or columns, where possible.

   For more information on optimizing data sources for DirectQuery, see DirectQuery in SQL Server 2016 Analysis Services.
