Gatling for Scala-based load test

I have just assisted to a presentation of Gatling, a Scala/Akka-based framework to do mainly HTTP load tests. It promises to scale EXTREMELY well, being based on the Actor Model, it doesn't consume 1 Thread per Virtual User, nor it blocks on I/O (don't ask me for details...)

What I like most is that your tests are written in Scala, so fully refactorable using any Scala IDE (Idea, Eclipse) and fully customizable. No need to reinvent the wheel, just use a solid one that most people already know.

Thank you Nicolas Remond for the excellent demo!
