They literally complain about that in yhe tweet I linked. That they spend 11 ms in React and only have 5ms to do the impossibly hard task of outputting a few characters on screen.

> Even if it takes 1ms total as long as that is under 16 ms that is fine.

How is it fine when you can re-render the entire terminal in microseconds (I also linked a demo for that, too), and they take 11 milliseconds just "constructing React scene"?

It doesn't matter if they take 12ms to render or 16ms. You're completely missing the point.
