I've read comments online (here on HN) that Github has been rewriting their UI in React and that it's got slower since. I have no knowledge if this is true or not (ie React -> speed direct correlation), and my own projects are small enough not to see any performance impact.

Does anyone have concrete information?

They just pushed a new redesigned page for pull request diffs- must have bloated the DOM.

I still see a little "try the new experience" link on the PR diff page (top right of page) so the rollout might be gradual. I won't click.

I tried it! I like it generally, but it’s too buggy. The whole diff explodes if you expand to more lines (for example). It’s easy to switch back.
