Why is loading/refreshing data in powerbi cloud or same problem also in desktop so slow ?
What I recommend to you in developing report is to use only tables and columns you need.
Your RAM spending = SUM of memory size of each field together
If you decrease number of columns using SQL then you will decrease it very much.
When you connect to your SQL Server/Azure SQL Database you can mention SQL script as shown below. It can be simple SELECT or something complicated as stored procedure which returns dataset
(In case of Analysis Services it can be written in MDX or DAX)
The best solution is this one.

Now it works perfectly, everyrefresh/changing parameters in visualization takes 1-2 seconds.... I can consider this link as a solution for everybody who has problem with slow PBI with a lot of tables.
I have maybe 10 bookeepings joined in one table now, 10 tables of invoices joined in one table and so.... one added column in table to indentify company. And all those sources have in querries turn off "enable load" option (so total refresh is working but it is slowing down powerBI).
Hi zoloturu
I can see the benefits here however it's inconvinient because I'll have to go into each report, set the option and publish it again. The manual part of this job bears the inconvience.
Anonymous,
Do you look into speed improvement on reports in Power BI Service only? (Do not tuch Desktop and republish)?
If so, then you need to buy capacity:
- Power BI Embedded (on the Azure portal)
- Power BI Premium (on the Office 365 portal)
Then go to Power BI Service -> Settings -> Admin portal to assign your workspaces to capacity
We are yet to buy capacity therefore cannot try that option. However; even if we had bought capacity, I wouldn't be keen to try that option simply because it creates governance issues. It will cause PBIXs to get out of sync with published reports.
