This is why node is powerful when used with AWS Lambda, you can treat CPU bound tasks as if they were IO. You can also do this by routing the job to a different processor on the same machine. Node is best when used as a relay or hub between many services and clients. Let those services do the computing work, let node manage everything and do the IO work. Node is kind of like an airport. Airports let you order food, alcohol, and even other cities. But as soon as you order, all of the work is offloaded to a third party -- the restaurant, the bar, or the airplane -- allowing the airport to handle someone else.
