I did a performance test last year, rendering thousands of views, and Flutter's rendering speed was 5 times faster than React Native. I wonder if this version will be improved after the update. Interestingly, I used React on the web to render the same number of views, and its speed was much faster than React Native.

I'm telling you, Flutter has amazing performance (+ incredible dev experience).
OK,just now I tested the new version and it is still slow.

Use "npx create-expo-app@latest --template default@beta" to install new version. Start with production mode, using android device, it takes about 300ms to render 2000 Views. The same test on React web is still much faster.

I'm speaking out of turn here since I'm not a React Native developer but, it seems to me that it suffers from the penalty of having to use the JS bridge that neither Flutter nor web use.
In the post we explain that this release removes the bridge, so the JS thread calls C++ directly without a queue, serialization, or bridge: https://reactnative.dev/blog/2024/10/23/the-new-architecture...
Thanks for the clarification.
