Slow DAX Formula Bar Input (Intellisense)

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 text input in formula bar for the measure.


Anyone experiencing the same issue or have the fix?

 

Already tried to change some options on Power BI Desktop and reinstalling. It improved a bit, but still lagging.

 

Thanks,

Guilherme

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.

Hi @guillouzada ,

 

Haven't experienced this issues before at my end.

Is their any screesnhot you can share? Is the load time for formula bar taking a lot of time?

 

Thanks,

Pragati

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.

 

 

 

Hi @guillouzada ,

Currently the DAX Formula Bar is expanded automatically by your dax statement and can only be zoomed. If you think the formula is slow, perhaps you can try to write it in DAX studio and paste it in power bi desktop to check whether it could help you.

Hello @v-yingjl ,

 

Sure it could be a workaround but not a solution, right? While I don't find any I can sure use DAX Studio.

 

Thank you!
