Github user michaelandrepearce commented on the issue: https://github.com/apache/activemq-artemis/pull/2482 Just looking over this a bit more. As the page ref needs to be a small as possible. The whole point of paging is to remove it from memory to be able to scale. With regards to priority i dont see this being accessed or affecting a hot path its only on access to message references. In regards to a consumer closing and having unhandled messages. This isnt on hot path imo, and shouldnt be tuning for that.
