I guess I don't understand - is this meant to be an object lesson or warning to people against using the wrong tool for a given application? The author self-identifies their problem as: "The problem I have is processing a lot of data quickly" Clearly, then, don't use node. But why write a blog post about not using something? A post involving a lesson learned ("I tried using node for processing a lot of data quickly, and it was terrible!") would have been more valuable. I fully offer up the idea that I may have missed the point.
