Hi, I'm doing nothing in the third actor. Once received the message is simple discarded. I'm simply doing a tell on the actor and passing the message through it.
One of the major reasons I posted this thread was to help my self understand the Visual VM. I'm not clear what the various dispatcher with numbers that appear in my snapshot signify. What are these entries? Why are the there? My code is using single ActorSystem.
