Best Practices for Optimizing Power BI Performance
Optimizing Power BI performance is crucial for ensuring that reports load quickly and provide accurate insights. Here are some best practices to follow:
1. Efficient Data Modeling
- Use star schema design to organize your data model.
- Avoid using too many calculated columns; prefer measures instead.
- Reduce the size of your data model by filtering unnecessary rows and columns.
2. Optimizing DAX Queries
- Use star schema design to organize your data model.
- Avoid using too many calculated columns; prefer measures instead.
- Reduce the size of your data model by filtering unnecessary rows and columns.
3. Managing Data Refresh
- Schedule data refresh during off-peak hours to avoid performance bottlenecks.
- Use incremental refresh for large datasets.
- Monitor refresh history to troubleshoot and optimize data refresh times.
4. Reducing Report Load Time
- Limit the number of visuals on a single report page.
- Use bookmarks and buttons to create multi-page reports with a cleaner design.
- Optimize the use of visuals like cards and KPIs to reduce the processing load.
