Reports performance with licensed concurrent users

Hi, gcanelon 

I think that if you import mode, the risk of performance issues can be very low. Because all data is cached in power bi service. If the report is using Direct Query to on-premise datasource and a large number of users are accessing that report then I would expect some performance issues since each time user interacts with visual on report query is sent on-premise to datasource.

What’s more, I suggest you set the scheduled refresh in the period of idle time(like midnight). In order to ensure sufficient memory space and higher refresh efficiency.

More advice of data refresh you can take
