Agreed, but why use Node if performance was so critical to your use case? Could this 400M insert logic exist in a separate service that lives outside your Node code base?

It's one thing to write a web service in a different language for performance; it's a much bigger question to move logic from your client to your server for the sake of performance. Both from a user experience standpoint and from an architectural complexity standpoint.

Not sure what you're getting at. Could you elaborate?
