The delay in increment/decrement example is not acceptable for a web UI that is expected to update instantly. I believe it should be less than 150ms to become noticeable for the user.

Not a great workaround, now I can't see the number I'm selecting. With the 500ms render time, it's going to feel really slow to pick a value. The perf needs to be fixed for this to be usable.
