Keith Wall created QPID-6803:
--------------------------------
Summary: ByteBuffer slices/duplicates contribute significantly to
garbage overhead in busy Brokers
Key: QPID-6803
URL: https://issues.apache.org/jira/browse/QPID-6803
Project: Qpid
Issue Type: Bug
Components: Java Broker
Reporter: Keith Wall
Profile whilst running auto-ack/transacted test at higher messages rates shows
that the garbage collection is dominated being dominated by DIrectByteBuffers
resulting from slicing/duplicating.
We could refactor QpidByteBuffer (maintaining our own remaining/capacity/limit
and keeping a reference to the original buffer) ourselves to avoid this
overhead.
