Eugene Meidinger, aka SQLGene.com, makes Power BI concepts easy and accessible. He’s got a free introduction to Power BI performance tuning here. People come to him with questions like:
What kind of tools are there for performance tuning Power BI? Where should I do my logic: SQL, Power Query, or DAX? What are some best practices for designing a data model? What is the best trick for speeding up Power Query? How do you get started improving Power Performance?
He’s joining me for Office Hours on Wednesday to take your Power BI performance tuning questions.
