He put better words to many concepts I've worked on for years, in simpler terms that what other languages have and/or could express. Has me very excited for Noria.
As others have commented though, the 25M ops/sec is a little confusing, it is certainly better than modern/legacy systems, but it is subpar for other recent/similar research and production systems (like ours). Theirs is about 2X Redis, but should be capable with that threading and type of machines of ~300M+ ops/sec, unless their cached reads were on very large values (but he says in the talk it is on Reddit-like messages, so it can't be) or if benchmarked relative to the client and it is including roundtrip latency to local server.
Either way, the quality of the ideas, work, and presentation certainly strike me as Jon or Noria is an up and coming smash success to keep an eye on.
