I am currently in the process of planning a large project for the company that I work for involving refactoring how our UI is rendered. Our goal is for optimal page performance with React.js while also not hamstringing SEO. I have heard a lot of issues with the performance of server side rendering with React before version 16.
I was wondering if anyone can give me some insight into the performance of server side rendering with React 16. Under load, does React 16 need the same performance workarounds that had to be done with previous versions? For large web pages, with a lot of DOM nodes, does server side rendering with React 16 still have a substantial performance bottleneck for concurrent users?
I really appreciate any information that can be provided.
