Akka Dispatcher

The engine of Akka as it decides when a actor should process messsages and when it must yield the thread for others. It means that dispatchers are in control of the thread time and of the threads themselves.

• Dispatcher (default): Event-driven dispatcher, sharing threads from thread pool.
• PinnedDispatcher: Dedicated thread per actor.
• CallingThreadDispatcher: Just for testing.

The best tips are:

• Adjust throughput to deliver more messages to the actors before yielding.
• Adjust dispatcher settings according to the use-case.
