With the introduction of improvements in the server notification time, we are happy to announce the removal of the delivery delay for message queue messages. With that, we have also removed the property

queue.default.delivery.delay inserver.properties

introduced with the release of Product 360 10.0, which results in a much faster execution experience of single message queue calls in multi-server deployments. In case the property has been modified in your deployment, we strongly recommend removing it to benefit from the new performance.
