I'm sorry the article wasn't up to your standards.
In fact I gave up around the insults at various Express-successors, and missed that the main point of the article is the µWebSockets.js.
Why not go into that directly and skip the rest? That's what people would want to know, not that "Node is worse than Golang in raw performance".
It didn't seem to point to some novel work, just to be some kind of piss take on Node.
