I have been playing with the API, and there is one change that would make the API clearer IMO.
Right now you have to send a delivery, and then call send(bytes) to add Bytes to the delivery what will make it copy data to the Delivery and self expand the buffer. I have played with a change that made it 5% faster than the most optimal way to expand the payload on the Delivery (using the same buffer over and over) And 15% on a brief calculation against creating the buffer every time... but there are cases where this could be a bit worse. Basically I have created an interface called Payload, and added a method setPayload on Delivery. I'm not sure yet how I would implement framing into multiple packages.. but I think it could be done.. this is just a prototyped idea: https://github.com/clebertsuconic/qpid-proton/commit/02abe61fc54911955ddcce77b792a153c5476aef in case you want to fetch the buffer from my git, it's this branch: https://github.com/clebertsuconic/qpid-proton/tree/payload In any case I liked the idea of the setPayload better than sender.send(bytes) to set the payload of a message. Ideas?
