5 minute real-world performance test: I just upgraded a relatively large (200K+ LOC) app that performs server side rendering of charts from React 15.6 to 16.0. Render time dropped from ~50ms to ~15ms. The previous version was already optimized and precompiled (e.g. none of the process.env performance penalties were applicable).
Very impressive improvement for a drop-in upgrade! Especially considering the previous version was not considered slow at all given the complexity.
