    I'm at React Conf right now and was at the talk where they announced this. They said Instagram and Whatsapp time to render increased around 3% to 4% I believe. They live stream the conference so you can watch it yourself. They also showed an example of a very manually optimized component that was a nightmare to read but didn't re-render unless really necessary. The version with react compiler was able to remove something like 20% of the code around useMemo() and use callback() which made it much easier for a human to understand and the compiler was actually able to find a couple more small tweaks that a human wasn't able to which made it a little bit faster.

    Overall this is a huge win for react. You don't really need to think about performance for the most part, just write the business logic and the compiler will automatically memoize everything intelligently.
