>
> Comparing the footprints of AMQP 1.0 protocol objects with the older 
> protocols shows that the 1.0 counterparts are larger. Some tuning would be 
> beneficial. For instance, the {{_sendingSessions}} and {{_receivingSessions}} 
> arrays are channel max sized, even if the client never uses that many 
> sessions.
> *Implementation*
> 1) ValueWriter can be optionally cached in AMQFrame. This would prevent 
> repeated writer lookup
> 2) Continuation transfers in Session_1_0 can be optimized to not call 
> continuationTransfer.setPayload() / continuationTransfer.dispose() . This 
> will prevent buffer duplication and disposal.
> 3) Fast-path for "body only" case in ConsumerTarget_1_0 can be added
> 4) Fast-path for 0 / 1 transfers in Delivery can be added
> 5) SectionDecoderImpl can be cached
> 6) MessageConverter_from_1_0 / MessageConverter_to_1_0 can be optimized to 
> avoid new objects creation
> 7) "Acceptance" outcome can be used as a singleton
