Hi there,
I have tried to load my query first time without added to Data Model and loading speed is lightning fast. Later, I loaded the same query again with added to Data Model and the loading speed is taking forever to finish.
May I know why and what has caused such drastic change in loading performance? Thank you
Regards,
M
The Power Query UI only loads previews of the data sources (query folding permitting). Once you load into Power BI / the data model then all the data is loaded.
