What does performance optimization mean in analytics solutions?

< 1 min read

Performance optimization in analytics solutions means improving speed, efficiency, and scalability of reports.
In my project, we optimized Power BI dashboards by reducing unnecessary columns and measures.
We removed unused visuals and minimized heavy DAX calculations.
Large datasets were aggregated at source level instead of calculating everything in the report.
We ensured proper data model design using star schema to improve query performance.
Indexes and optimized SQL queries were implemented at the database level.
We also monitored refresh duration and reduced data load frequency where possible.
Overall, the goal is to deliver faster load time and smooth user experience.
