It’s an interesting question. When it comes to processing large amounts of data I’d actually be more concerned about JavaScript’s memory usage than strict processing performance. Certainly you could use JS smartly with typed arrays and such to minimise memory impact but you'd basically be manually creating a lot of the convenience that Rust gives you out of the box.
