What is Import mode performance behavior?

< 1 min read

Import mode performance behavior means data is loaded into Power BI memory for fast querying.
In my project, reports using Import mode loaded faster because data was stored in the in-memory engine.
Query response time was quick since it did not hit the database repeatedly.
However, performance depends on model size and available memory capacity.
Large datasets increased refresh time because full data reload was required.
Complex DAX calculations impacted performance during user interactions.
We optimized by reducing model size and using aggregations.
Overall, Import mode provides fast report interaction but requires careful memory management.
