Jeremy, are you saying that 3 node processes on three dedicated machines is faster than one node process on one beefy machine?
If you want to use all n cores on a machine you need n node processes on that machine. And yes, node is mostly single threaded. Some things like fs.* and zlib.* use a thread-pool so that they don't block the main thread, but your js code will always run in the main thread.
