React
I've been testing the new useTransition hook in React 19 and noticed significant performance degradation when handling large datasets. The transitions seem to block the UI longer than expected, especially with concurrent rendering enabled. Has anyone else experienced this? Looking for optimization strategies or potential workarounds.

We encountered this in production. Ended up implementing a custom scheduler with time-slicing. Happy to share our solution if you're interested!

This might be related to the concurrent features. Have you tried using startTransition more selectively? Sometimes batching multiple state updates can help.

I've seen similar issues! Try wrapping your heavy computations in useMemo and make sure you're not triggering transitions unnecessarily. Also check if you have any blocking operations in your transition callbacks.
