> 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.
