What is interesting here is to compare this one man's effort with "ancient tools" well-researched by two generations of old-school programmers with that amateurish hype and nonsense about node (author publicly stated in his blog that he has no experience with server side development on a POSIX system) and golang - a minimalist approach, carefully crafted by a rigorously trained "professionals". It is not just about KBs and milliseconds.<p>Btw, this "Hello world" example tells a little, basically, how efficiently memory allocation, and IO layer are implemented (that's why no one still could beat nginx).<p>Much more interesting comparison would be of some "real-world scenario", say, "implement an http look up for some public data-set, imported into a <i>persistent</i> local storage, say, Postgresql" and then compare not just throughput rates, but also resource usage.
