This question is all over

And did you see the performance changes in your project

Well, it depends on what (and how) you are doing with that data. If you are doing stuff in the compose block, then you are going to see multiple recompositions if you didn't `remember` it. Anyway, you are supposed to use a view model for these kinds of stuff.

`rememberSavable` (by default) will also not help you in this case, as it would need a custom saver that you need to pass to make it "remember" across config changes or recompositions.
