"With node.js you don't worry about performance (...)"
"Now we know that we can easily write well performing servers (...)"
these kind of statements are why i rarely read nodejs articles nowadays. you can't just say that in general.

Sure, if you hit it big, you'll probably need to change things around a bit. But I think its valid to say that with Node, you don't have to worry about performance because by default its really, really fast.
Overall I have mixed feeling with my experience with Node so far (the libraries are very young, and extremely flaky). However it makes it dead simple to write apps that scale to a ridiculous level without huge amounts of upfront planning.
Performance and scalability are not always a tradeoff. When you increase performance at the runtime level, you don't decrease scalability. However it allows you to serve more requests in the same amount of time.
