Direct Query taking unreasonably long
Hi scoobyloong
DirectQuery is a direct connection to data source. Data will NOT be stored in Power BI model.
Power BI will be a visualization layer, then query the data from data source every time.
In the DirectQuery case, when users visit a Power BI report, Power BI sends queries in real time to the underlying data source.
Once the data source returns with the query data, then the report is rendered.
As a result, your report performance in these cases depends largely on the performance of the underlying data source.

You could Use Performance Analyzer to examine report element performance
With DAX Studio, you could analyze DAX queries for performance issues, and improve the writing of DAX queries.
