Hi everybody,
I have a dashboard that is getting data from multiple SharePoint lists. Some of these lists contain around 3000 to 4000 lines. When I want to refresh my dashboard it takes about 3 minutes. A list with about 3000 lines is easily around 10mb (which I find quite large). Some lists contain quite a lot of lookup columns that get information from different lists. I am using the standard 'SharePoint list' connector provided by PowerBI and my lists are coming from a on-prem SharePoint.
I find it odd that this refresh should take so long, I am doing some operations on my queries to clean op the data, but no really heavy ones such as expanding and merging. I have the impression the downoading of a 10mb list takes a lot of time even though my internet connection itself is quite fast.
Attached you can see a screenshot of my 'Data Load Settings', these should all be optimal for speedy refreshing.
Could anyone please help me understand why this is happening. I tried cleaning up my queries and removing columns I'm not using, unfortunately without much succes.
Kind regards,
Matt
