"deliver performance" is too abstract. I usually throw varnish in front of my ruby apps to get performance. I find this gives me a more productive programming environment (ruby), and insane performance.

Node only becomes useful for me when I need to keep a lot of connections open and handle them simultaneously, and a few other rare situations like that.

Performance is one of the few legitimate arguments the Node community makes. It is wicked fast out-of-the-box compared to Ruby out-of-the-box.

Unfortunately there are many other factors involved in building software that matter as well.
