Do you want 5 API instances sitting in front of your DB or one? Do you want to optimize your code when your GC'd code isn't fast enough or not? Do you want every request to the backend to take 50ms less time?

So, if your answer to the question, "Do you want speed, trivially?" is "No, I do not." Ok.
