Went to your docs, saw the counter, pressed the button and saw a delay on increment when clicking a button (the simplest utility imaginable).
I don't want to hate, but if THIS has delay I don't even want to think about more complex state updates.
We are working on improving the performance, we are still pretty new but there are a few different ways we can speed state updates up. For state updates like pressing the counter a lot of times it can been seen, we will improve this.
