> NodeJS performance is hampered by its single-threaded architecture, but given that fact it performs very well. The NodeJS server was the smallest overall in lines of code and extremely quick and easy to write. Javascript is the lingua franca for web development, so NodeJS is probably the easiest platform for which to hire or train developers.
Do you actually read the blog post before making the claim ? The author is not using "Cluster" module to scale connections across CPUs with "Sticky-session" library. Also, neither he mentioned the runtime flags with which the launched all VMs in comparison nor he mentioned the optimization at OS level.
I expected all benchmarks that use the (linux) kernel for I/O events would perform similarly. The code is so small that the interpreter overhead should not degrade the performance too much. May be the JSON parsing / serialization?
