Hard to say what's going on there. Vert.x itself is quite speedy. The DB access module they use (http://vertx.io/docs/vertx-mysql-postgresql-client/java/) is still in technical preview so there may be legitimate issue with the module or something wrong being done (I only glanced quickly and didn't see anything immediately obvious). Vert.x really isn't much more than a pleasant facade over Netty so it's hard to imagine what's actually wrong.
Personally, I don't really care about benchmarks. Getting stuff done is more important at this stage. Eventually this may become more important but I'm not going to worry about it until it becomes and issue for us specifically.
It appears there may be an issue with the benchmark? https://github.com/TechEmpower/FrameworkBenchmarks/issues/21...
