[jira] [Created] (ARTEMIS-3449) Speedup AMQP large message streaming

Francesco Nigro created ARTEMIS-3449:
----------------------------------------

             Summary: Speedup AMQP large message streaming
                 Key: ARTEMIS-3449
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3449
             Project: ActiveMQ Artemis
          Issue Type: Improvement
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


AMQP is using heap ByteBuffer(s) to stream AMQP large messages: given that the underline NIO sequential file can both use FileChannel or RandomAccessFile (depending if the ByteBuffer used is direct/heap based), both approaches would benefit from using direct ByteBuffers pooled from Netty and save additional copies (performed by RandomAccessFile) to happen, reducing GC too.
