> Key: QPID-7754
> URL: https://issues.apache.org/jira/browse/QPID-7754
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.0, qpid-java-6.1
> Reporter: Keith Wall
>
> A consequence of the direct buffer strategy currently employed by the Broker
> is that if a producing application uses a new connection per message, then
> each message holds an additional {{256K - payload/header size}} bytes of
> direct memory unused until the message is consumed. The worst case is for
> small messages, where the waste is at its most.
