title: scala/akka performance versus java 7 fork/join
body: <p>I am new to Scala/Akka, although I am very well familiar with the concept of actor-based modeling. I am trying to parallelize an existing code for better performance, and I have two versions: one in Scala/Akka and one in Java 7's ForkJoinPool.</p>
  
  <p>I was expecting that the actor-based approach should be faster, but the result is the other way round. It is something like 20 sec for Scala/Akka versus 17 sec for Java fork/join.</p>
  
  <p>I'd like to know if akka is intrinsically slower? Or could it be because I am using the classes from the existing code written in normal Java in my both implementations?</p>
