Semantic model taking time to refresh on service from January 2025

[ankgupta4]

Refresh of my many semantic models on Power BI service is very slow since 4th January 2025. Normally, a Semantic model which usually takes 2 min to refresh is taking approx 1 hr 30 min to refresh starting from 4th January 2025.

Hi @ankgupta4 ,

There could be multiple factors.

1. What is the size of your semantic model?

2. There could be an issue with your capacity limit because of other power bi reports assigned to the same F-SKU premium capacity. Can you try refreshing it in non premium workspace or workspace using different FS KU/P 1.

3. Do you have any calculated columns which is creating performance issue during refresh?

Thanks,

Pallavi
