React/competitor performance that people use to compare frameworks is about rendering performance. E.g. React takes 100ms longer to rerender 10,000 elements (random numbers for the example). In these situations the actual real world difference will be negligible.
Site performance is much more API based, and that’s the same regardless of frontend. React has more library solutions to optimize the UX though, as it’s the most mature and popular.
