Known that what doesn't scale? Threads? Sure they do. I could have made Ruby threads work, I guarantee you. Move the network requests into a giant thread pool, and then do everything else synchronously. It was the context switching that was killing me, but you can use threads in such a way that that's not a problem. It's just a lot of work. More work than just using Node, which pretty much does exactly that for me for free.

And on a side note "your education has failed you"? Seriously? You can't just preface something with "I don't mean to be offensive" and then say whatever you like. I don't mean to be offensive, but get yourself some social skills.
