Go is generally faster, but if you have performance issues, the language may not be the first thing to look at. Look at your caching strategies, dependencies (APIs, databases), what could be static, etc. The frontend part is as important as the backend. For something written from scratch today, I would actually highly recommend a stack such as Remix. Everything feels super fast, not because of a language, but because of the framework design.
