We tried to throw Puma at Rails a few times. Would not recommend. If you're trying to add threading to a Ruby I would question how safe you really think dynamic languages are. Fortunately Ruby/Puma/Rails have been out of favor for a while, but if you're stuck with them, I'd just accept your 2-4x higher AWS bill for the hardware you need for Rails rather than add dangerous threading abstractions.
