Using your same link I find this solution blowing node away in JSON serialization but the other benchmarks? Not so much. In fact complete opposite for some of them.
As far as I have found there is no "best at everything" language and framework so your binary question doesn't make much sense. I'm also not convinced of this solution in a large web application because debugging and unit testing would be nightmare .
OpenResty is considerably faster than Node in the JSON serialization, single query, and plaintext benchmarks. It is slower than Node in the multiple queries benchmark, and missing from the other benchmarks.
So, it's a bit more inconclusive than you describe. I'd expect OpenResty to be much faster than Node for a lot of common web interactions. Node has better support for interacting with external services asynchronously, though.
