Not only that, but Node actually got faster as simultaneous connections increased while keeping a completely stable memory footprint. The benchmark showed the opposite of what the author claimed -- Node scaled effortlessly. Its performance was completely stable and predictable under load, whereas Go's wasn't.
Not to knock Go -- it's a beautiful language, and absolutely faster than Javascript for most purposes (and will no doubt increase in stability and speed as time goes on). But this post had some pretty flawed analysis of the benchmark presented.
