I’d love to see some rough numbers on what sort of performance gains one might expect in the real world. I understand this is peak “it depends” territory, but what gains did Facebook or early adopters report? Is there a trade-off to between first render cost and re-render speedup?

What we've generally found is that the bundle-size increase is quite small after gzip. We also saw that it wasn't just re-renders that got faster but also initial load, as often times components have to render multiple times even on the very first page load in order to fully settle.
