Since you mention scrolling, it sounds like you are rendering a lot of off-screen content... Have you looked into solutions like react-virtualized? It can definitely speed up the experience

It looks like React concurrent mode also deprioritizes the rendering of off-screen content for you. (I've been browsing the react reconciler source this morning...)

I haven't; the amount of magic going on makes me a little wary, but it does seem like it could be a good solution. Maybe I'll give it a try.

Lazy rendering is way less magic than this concurrent work, plus it's something that is usefull everywhere.

React concurrent mode does this out of the box from what I can see.
