exactly, it's logical, we need to iterate multiple folder and sub_folder fastway possible, and in eventsheet with vsync its limited to 60fps.
its not function list_content
It's not the list_content query that's slow, it's the iteration and even having to wait for the end of the query from 60 frames
Unity, Godot, Native Js with same filesystem service, doesn't have this problem with vsync enabled.
