The TechEmpower Web Framework Benchmarks score Java 5X faster than Erlang at a simple JSON test. (There's an even simpler plaintext test but no one was implemented it for Erlang.)

However it's worth nothing the test only runs for 15 seconds. It might be an interesting addition to run it for 10 minutes and measure 99.9% latency, as jlouis proposes, and prove one of you correct.

It also shows that Erlang is 15X faster than Java (depending on what framework you compare) and that the Java Netty/JSON test has 8X more code than the Erlang Cowboy/JSON counterpart ;)

That's nonsense. jlouis challenged us to "Take the fastest webserver written for Java and for Erlang", not the slowest ones. And that's exactly what the TechEmpower benchmarks do and they give Java a ~500% advantage.

As for codesize, if you don't like netty then the very next ranked result is servlet3-cass which delivers nearly the same performance -- again, approx 5X faster than the fastest Erlang impl -- in just a few lines of code. Surely you were aware of this when you wrote that comment.

There was a smiley in the end you know... My point was that these "tests" really shows nothing. It's a very specific scenario and if you read the comment from jlouis you would know that his scenario was very different and would yield a different result.
