Part of the goal was fixing this without having to just throw hardware at it. Every Node process has a non-trivial amount of overhead that requires additional hardware resources. Overhead that the Go app doesn't have. They could have thrown more machines at this but that costs money. The better solution technology wise was Go. It was better suited to their workload.
