With respect to the TechEmpower benchmarks, if you look at Round 13 [1] they note that ASP.NET got 859 times faster in their benchmarks since Microsoft dedicated effort to improving it.

Indeed (though it's worth noting that they're talking about the performance of ASP.NET Core versus Mono, which was notoriously disastrous performance wise, and that story got somewhat misrepresented). In no way am I saying that the .NET Core is slow.

But if we want to use that benchmark, doing the most trivial useful thing of all -- serializing a simple object to JSON -- and node.js beat core .net. In the recent iteration it beat it by almost 2x (which makes the "node.js is slow we all know that" bit in the linked piece humorous given that it beats aspnetcore in every test but plaintext, which is an irrelevant test anyways given that they put their service behind nginx).

I don't use node.js. I don't advocate it. I personally think most node.js solutions end up being a spaghetti mess. But these sorts of "the details are hidden but look at the magic we wrought!" benchmarks are worse than useless. They're fools gold for people choosing platforms and thinking this sort of advocacy is guidance to learn from.
