Power BI report optimization - Connection question

Hi.
I have developed a report in Power BI desktop that will be published in Power BI Service, so i need it to be as optimized as possible.

The data sources of the report are excel files stored in Sharepoint. I would like to know which is the best option to get the best optimization and performance of the report:

1) connect to Sharepoint through a Web connection, using the sharepoint URL (Get data -> Web)

2) connect directly to the Sharepoint folder (Get Data -> Sharepoint Folder)

Thanks in advance!
