Helper IPowerBI Desktop - refresh too long under evaluating
Hi leandroduarte ,
Too large data model and complex relationships could cause power bi load data models slowly.
Besides trying to disable Auto detect relationships in power bi, you can try to reduce the size of your data model for unnecessary data, optimize data types etc.
Plesae refer these documents about optimize data model in power bi:
- Data reduction techniques for Import modeling
- Optimization guide for Power BI
- Optimize a model for performance in Power BI
