Loading multiple JSON files from Azure blob storage slows down the performance

[SachinMohanty]

Hi,

 I have developed a solution in Power BI using power query to load multiple JSON files in Azure blob storage to Power BI dashboard.

I deployed the dashboard in power bi workspace.

Initially the dataset refresh was quick with less no. of files.

Eventually when the no. of files started growing in the azure blob storage, the duration to load the data also started increasing. 

Could you please advise any alternative solution to load the dataset quickly.

Regards,
Sachin

Hi @SachinMohanty ,

Actually, I'm afraid that this performance is normal as your dataset is coming larger.

In addition, the performance should be affacted by many factors such as the network or how many visuals you used in this report and if your measures or calculated columns are complex.

If you want to improve the performance, please refer to this document.
