Any info on the performance of react-three-renderer? Does it make things slower / quicker compared to similar setups with only three.js ?

Two of the linked examples are benchmarks that let you compare the React renderer with direct updates. I saw no difference (both were at 60 fps for me).

Did you try increasing the amount of cubes? There's a dropdown at the top.

React drops to ~30fps for me on 1500 cubes, direct update stays at a solid 60fps. The delta increases as cube count increases.

Indeed. For me at 500 cubes, React is already about 2x slower (44fps -> 23fps).
