I am adding new attributes for our project & we found out that there are around 150 attributes we might need to add. Is there any possibility that it'll be slower to return experiments or feature flags compared to 20 attributes? I'm talking about only adding attributes to growthbook once our app loads using growthbook.setAttributes If there's any chance of it, then how many attributes are recommended to be added?

No, that will make almost no difference

Thank you
