Hi @Anonymous ,

According to my understanding, you want to know how to reduce the data refresh time in Power Bi Desktop,right?

When you do joins/appends in Power Query it has to load the entire table into virtual memory. This causes a lot of paging and is very slow. 

You could change your data model,  uncheck the Enable load option for the unnecessary table

For more information,you can refer to:
