In Power BI Desktop DAX formula bar text input is very slow for bigger measures (greater than 50 lines). And it gets worst with measure size increase. This is NOT the measure performance but the tex...

    Hi guillouzada ,

    Based on my test, DAX studio works better than power bi when writing more than hundreds rows of DAX statement in this case, so I think could be a solution to help you.

Actually this is slow while typing the text. The time to load the formula bar or accepting changes (click ok/enter) are fine.

 

Here's a video of the issue.

Hi guillouzada ,

 

This seems to be more like the issue regarding volume of data behind your Power BI file.

What size of data are you working with?

    @Pragati11 ,

    Thank you for helping me. Really appreciate 🙂

    If I create a new measure or even a new column with few lines the formula bar runs smooth and fast.

    The main problem is with the calculated table formula that has 1500+ lines.

    This table has only 731 rows. And it's a calculated table.

    Here's the pbix file properties:

      Hi guillouzada ,

       

      Just thinking now if is it really right to create a 1500+ lines of DAX code for a calculated table in Power BI.

      What's the requirement that is making you do that?

        This case is only an example for my issue but I have other with big measures also.

         

        I use those for measures and visuals performance improvement. Some cases that I'd use 30+ cards in the same page I can use only 1 visual with HTML. In this one we could drop the refresh time from 30s to 50~100ms.
