How to optimize semantic model
Hi minhnhatdanchoi ,

If this response was helpful in any way, I’d gladly accept a 👍much like the joy of seeing a DAX measure work first time without needing another FILTER.
Please mark it as the correct solution. It helps other community members find their way faster (and saves them from another endless loop 🌀.
Hi minhnhatdanchoi,
Monitor memory usage using the Capacity Metrics App. If your semantic model needs more RAM, you may need to upgrade your capacity. To enhance performance, try reducing the dataset size and use model optimization methods like aggregations or DirectQuery for large tables. Power BI does not show memory usage for individual visuals or measures.
Thank you.
My semantic model already used Direct Lake, my table contains 5 millions rows
Hi minhnhatdanchoi,
Key Best PracticeFiltering at ingestion or using aggregations is far more effective than relying on slicers because slicers still load the full dataset before applying filters.Optimise the Semantic Model- Remove unnecessary columns.
- Use aggregated tables for historical data (e.g., monthly summaries instead of raw rows).
- Avoid calculated columns on large tables; prefer measures.
- Consider incremental refresh with Direct Lake to keep only recent partitions active.
- Consider incremental refresh with Direct Lake to keep only recent partitions active.
I'm curious about this, how can I set-up this to my model ?
