Sharepoint Datasource slow refresh

Hello,

 

I have a lot of my dashboards connected to Excel files in Sharepoint, since a week everything is slow : data update & preview in power query. Everything was really quick before and no change were made in power query. 

It takes an hour to get refresh completed. Is there a global issue on Power BI or Sharepoint side ? 

 

Thank you,

Regards

Note that you can leverage incremental refresh with Excel files on SharePoint, if applicable.
