This is really exciting! Concurrent Mode has the potential to improve the user experience significantly.

Well, I tried implementing Concurrent Mode in a simple project. But, I couldn't measure any performance improvements. Does someone know if @facebook has any official performance benchmarks?

Concurrent Mode isn't fundamentally about improving rendering speed. It's more about improving responsiveness during unit-of-work scheduling.

Just to add, Concurrent Mode allows React to suspend rendering early in order to prioritize something newer. This leads to smooth transitions and improved user experience.

The docs indicate that Concurrent Mode is still under development and experimental. Does anyone have any insight on a release timeline or best practices until then?

One unofficial blog suggests that Concurrent Mode might show up in the next major update, version 17. But I wouldn't rely on that as Facebook's release cycle isn't set in stone.

React team member @acdlite mentioned here on Twitter that they are close to launching a 17alpha with Concurrent Mode included: <https://twitter.com/acdlite>

Totally agree with John here! I'm looking forward to implementing it in my projects.

Have you tried using @google's Lighthouse tool to measure performance?

Right, it improves the user experience. It now enables us to run multiple updates without blocking the DOM queue, thus making the app look more responsive.
