There are definitely going to be things that Node is slower for, and others that it excels at.. just like everything else. I would recommend anyone that is wondering about this to check out this great presentation given by Ryan Dahl, the creator of Node, in which it talks about the concurrency model, how it is acheived, and what the consequences of this are. The short story is that Node performs well under high concurrency and and IO bound workload with lots of small files. It is not going to excel so much for a computationally bounded or at serving huge files. It's always going to be about knowing which is the best technology for the job at hand. http://nodejs.org/jsconf2010.pdf http://nodejs.org/jsconf2010.pdf
