Increasing performance of a desktop report

[Matthias93]

Hi,

I currently have a dashboard based on 5 excels and 10 SharePoint lists. To increase the speed of this report I have done mulitple things: 

• Deleted columns I don't need (will it make a difference if it is het last of the applied steps on a query or if you do it when loading the query?)
• Fiddled with the data load settings (no preview loading and no data/time loading)
• Minimized string columns to a certain extend

After doing this the report is still quite slow. Note that the lists and excels are very small at the moment. No more than 10 lines each. With no query having more than 10 columns. I do have a fair amount of slicers on each page (around 6) and read that this could slow down performance. I also have some measures using the 'filter' function, but find no other way of writing them. 

Does anyone have any experience with this? And how have you resolved it?

Kind regards,
Matt
