That's not to say that v8 isn't fast or that you can't do good science with javascript, it's to say that big problems need big iron. Of course, when it comes to making native modules in node, v8 is at a disadvantage to, say, python, when it comes to the speed of the interface. I love javascript, but unfortunately that's the reality of things. Personally, my approach has typically been to use node for juggling IO, and then delegating the "hard stuff" to basic services written in "more appropriate" environments.
