Rust is no panacea and rewriting a web application in Rust should not lead to any performance gains per se, unless your web application is doing number crunching in the mouse move handler. In most cases, you should be lucky to see no performance hits after a rewrite, because pleasing the borrow checker makes things unnecessarily more complicated.

A valid reason to switch to Rust should be a better developer experience, but it will require lots of upfront effort to realize the benefits. I doubt that it's worth it for small to medium-sized web applications.

Also, React itself is very much lightweight and fast, it's the developers who use it to program slow websites.
