Are you using the latest version of Power BI Desktop? I found earlier versions to be slow but now they are quite snappy.

You probably will want to get a Gateway setup. They are pretty handy.

I am using the most recent version of the desktop app. I have a 64 bit machine with 8G of RAM and the appropriate version of Power BI desktop installed. Even with the gateway setup, I'll still have to set up the dataset and report in the desktop app before deploying it to the PowerBI server.

  alm5084,
  
  If dataset is large and you've used import you may have performance issue plus longer times for data refresh. DirectQuery would take away the need of data refresh but that means there maybe bit of delay in getting data for visuals as queries would be sent to on-premise data source. For example when you apply a filter queries would be sent to on-premise data source.
  
  In your scenario, Please try to use DirectQuery mode to get data in your Power BI report and check if this issue persists or not.

    I don't think there will be a huge performance difference between Power BI and Power Pivot. If it working with Power Pivot in 5 mins, will work with Power BI as well.
    
    We will see performance issue in a case of huge data, to avoid this. Use direct query and have gateway in place, which might solve your problem
