Ok I stand corrected. Some have mentioned the React layer is very thin it's mostly vanilla JS!

I think my point still stands that, if MSFT cared, it would be fast. The issue is not the technology choice in this case.

For example, look at their demo here: https://diffshub.com/oven-sh/bun/pull/30412

It's way faster than GitHub and you check the network tab.
