Hello everybody,
I've got my mashup evaluation container process never going above 10% cpu usage, it's taking hours doing some power query (non foldable in sql) functions. Do you have some hints to make it work faster? I cannot understand where the bottleneck is, RAM usage is low too. My pc is quite powerful, and when uploaded and refreshed through the gateway my model is a lot faster.
Thanks
Hi @AGo
There is a "Maximum memory used per simultaneous evaluation setting" in Power BI Desktop. See if this value is set too small. This only affects the working memory on your computer.

Hi @AGo
What is the source? some sources don't accept Native Queries...
Power Query is better used for ETL, don't try to do complex calculation with M code, Used DAX for complex calculations.
