Which is faster in terms of performance, applying filter in DAX or applying filter in visualization?

[Sreya]

I need to put filters on one column. I can do it two ways

i) Putting filter in measure calculation 

ii) Applying filter on visualization

Which approach is better in terms of performance?

Hey @Sreya ,

depends very much on the data model and the measure.

You have to test that with DAX Studio.

To be honest, if both slice the filter context based on relationships they should have a similar performance.

With DAX you can screw up easier by slicing on iterators for example, but if you know what you are doing you can also improve better. With the filter on visualization it's more likely to have a good performance as you just filter existing tables.

If you need any help please let me know.

If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
