title: What is the correct way to configure actors in Play 2.x?
body: <p>I noticed a slight difference between the documentation for 2.1 and 2.0:</p>
  
  <p><strong><a href="http://www.playframework.com/documentation/2.0/ScalaAkka" rel="nofollow">2.0</a></strong></p>
  
  <pre><code>akka.default-dispatcher.core-pool-size-max = 64
  akka.debug.receive = on
  </code></pre>
  
  <p><strong><a href="http://www.playframework.com/documentation/2.1.0/ScalaAkka" rel="nofollow">2.1</a></strong></p>
  
  <pre><code>akka.default-dispatcher.fork-join-executor.pool-size-max =64
  akka.actor.debug.receive = on
  </code></pre>
  
  <p><a href="http://doc.akka.io/docs/akka/snapshot/scala/dispatchers.html" rel="nofollow">Akka's own documentation</a> has a <code>core-pool-size-max</code> setting like 2.0, but no <code>pool-size-max</code> like 2.1. Why did this change between 2.0 and 2.1? Which is the correct way to configure Akka in Play? Is this a documentation bug in one of the versions?</p>
  
  <p>(In the meantime, I'm going to try and stick both config styles in my Play 2.1 config and hope for the best).</p>
