What is Power BI performance optimization conceptually?

< 1 min read

Power BI performance optimization means improving report speed, refresh time, and overall user experience.
In my project, we optimized by following a proper star schema instead of a flat table.
We removed unused columns and reduced high-cardinality fields.
Complex DAX measures were simplified to reduce calculation load.
We ensured filters were applied at source instead of loading full datasets.
Aggregations were created for large fact tables to improve query response time.
We limited heavy visuals and reduced unnecessary interactions between charts.
Overall, the focus is on efficient data model design, optimized queries, and faster report performance.
