Direct Query performance not as expected

[fguijarrob]

Hi,

I´m trying to get data from a DirectQuery from a SQL Server DB (14GB and 230k rows) but performance is not as expected. It takes more than 10 minutes to show data in the PowerBi report. How can I improve the performance? Server where DB has 16GB RAM and intel Xeon(4 cores). Power is being run from a 16GB Server Xeon 2 and I also assigned 8192MB cache from "cache management options".

Thank you for your help!

Optimizations need to be applied directly to the data source to achieve good performance results.There isn't specific to way to improve power bi performance, you need improve many aspects depends on your model.
