Looking at my Prometheus stats right now, I've got a Node TCP server doing 12k concurrent connections with 3-5% CPU and 130 MB memory. At least 4 DB queries are done per request, sometimes 10 queries. Raygun either has some nonobvious stuff going on, or Microsoft paid them to write PR fluff. After 6 years with Node it seems odd for their performance to be so bad. They should dive into more technical details to explain what specifically was made faster.

You've described a classic I/O bound server application (waiting on the database) that Node handles well. As soon as you introduce serious computations or server side rendering into the request handling performance would fall dramatically.

And Raygun, according to what the website says it does, is doing a significant amount of work.
