How fast get_simple_path of Navigation2D is? Can I use it asynchronously?

As I see in example, get_simple_path returns result immediately. But as I know, path finding usually takes a time. So, in my point of view, I should make a request of patch and then wait for success signal.

Does this function make delay in code execution? Is it possible to use it asynchronously?
