SharePoint Online slow refresh
Hi Anonymous ,
Please check whether there existing any step in Power Query cosuming too much cpu or memory. And try to use Table.Buffer to improve the data load performance.
SharePoint Online List- Power BI - slow query update

Hi Yuliana,
I do not have anything complicated happening on my queries.
This issue is replicated just by: New query -> SharePoint list -> Browse to list. That is all I am doing and it takes forever.
Another issue may be that SharePoint pulls all the data before filtering, unlike SQL

Will bump again.
Surely others using SharePoint Online have the same concern with how the standard PowerQuery (Excel & BI) downloads so much in file size and so slowly?
Again in Excel it can be worked around but not in BI as far as I can see, so refreshing datasets will just get slower and slower.
It seems that SharePoint online will not filter the data on the standard query until it has all been downloaded. I can see this by, in preview, when I filter a column and find it downloads the same file size again before completing the filter
