Obviously they did something terribly wrong in the first place and now are showing off being all right. Netty would probably faster. As there're no details at all, I feel free to just guess :-).

I recently found Node much faster then .NET Core for a very specific scenario:

Elasticsearch - Node / ASP.NET Core (Kestrel) - NGINX - Client

where every connection must be TLS. So, Node / ASP.NET Core have to decrypt traffic from Elasticsearch and encrypt to NGINX. For a minimal workload the whole trip took 50 ms with .NET Core and 20 ms with Node. Obviously there's something wrong with the .NET setup - maybe some setting with Kestrel and TLS.

Anyway, that's my anecdote. And I wouldn't dare writing a block post how node is 2,5 times faster than .NET.
