[jboss-dev-forums] [Design of Messaging on JBoss (Messaging/JBoss)] - Re: Paging, lastPageTransaction, and duplicate detection.

One thing that I realized by accident today: The duplicate detection is having a deep performance impact on paging. With the LastPage stuff we would only add one record per-page, and delete it as soon as we had the confirmation of commit, having a minimal impact on the journal. The duplicateID however, is storing one extra record perMessage. I know we will have the circularID and stuff, but that is just not as optimal wise as what we had before.
