> TransportConnection.dispatchQueue currently uses a synchronized LinkedList to pass all objects between the broker and the transport connection to the client. This isn't very efficient as the whole list is locked whenever an item is added or removed. ConcurrentLinkedQueue is about 20% faster in my tests.
