Power Bi App resource

jwo Non-Premium workspaces run in shared capacity. So, there's only a limited amount of resources available in shared capacity and probably even less resources for stuff like My Workspace versus Pro Workspaces. So, if lots of people get on the Service in the same Azure data center that your Power BI tenant is provised then its going to tax the shared resource capacity and things could get slow, even slower than usual for DirectQuery. A Premium workspace may have limited memory, etc. but it is optimized for enterprise workloads and you and only your users can access and use the capacity of your Premium capacities. So, you can't be affected by everyone else using Power BI if your reports and datasets live in the Premium capacity. That is not true if you leave your dataset in My Workspace. Honestly, I'm very surprised it works at all.
