Those type of frameworks are great, but they all have performance limitations. The typical solutions are either find a faster framework or write it by hand. If the issue is that it is blocking the event loop rather than the literal performance, then you could spawn a process to do the React work.

Thanks. Are there no background worker process packages for nodejs that might be able to queue up some tasks?

You want to search for "web worker" or "background task" in NPM.
