Willem, The 1000 milliseconds in the SedaConsumer.run() method is a timeout and not a delay. The javadoc says: "Retrieves and removes the head of this queue, waiting up to the specified wait time if necessary for an element to become available."
So if a message is available it will take it immediately.
