C++ vs NodeJS uWebSockets

[KamyarTaher]

Hello,

I need a backend with the best performance possible in terms of WebSocket connection/speed and mathematical computation.
So I found uWebSockets that seem to be very promising in terms of socket speed, then I come across the following article stating that C++ performs very poorly and Nodejs extremely well in terms of socket speed/connection.
Has anyone more information about this. Is this legit? How a lower-level language like C++ could perform worse than NodeJS?

Is this legit?

No, they obviously messed up. It makes no logical sense that the base library would perform worse than the wrapped up, scriptable variant that's using the base library.
