Github user franz1981 commented on the issue:

    This one, together with 
https://github.com/apache/activemq-artemis/pull/1916 aims to reduce the memoty 
footprint (improving scalability by different angles) of AMQP on the broker.
    I need a review from @clebertsuconic  and @tabish121 for the mechanics that 
I've used to reuse the same send buffer: the mechanics is solid but if 
`ProtonServerSenderContext.deliverMessage` would be already 
uncontended/single-threaded it could be simplified avoiding the 
`AtomicReference` usage.
