I have connected Excel file to Power BI Desktop. Excel file itself has about 10 tables and I am using formulas to get what I need in regards to calculations and stuff. My excel file is 10MB large. In Power BI Desktop, everything runs fine but once I publish report to Online version, Report and Dashboard are very slow. I have only 4 pages and about 15 charts total. It is slow to the point that it's worthless. It takes 10min (yes, I have used stop watch) to load the data before you can drill-down and filter your charts. Does anyone have any clue what’s going on?
I am using latest version of Power BI Desktop Version: 2.38.4491.282 64-bit (August, 2016)
