Summary: Perforamance improvements for transfer tag cache
Key: QPIDJMS-317
URL: https://issues.apache.org/jira/browse/QPIDJMS-317
Project: Qpid JMS
Issue Type: Improvement
Components: qpid-jms-client
Affects Versions: 0.24.0
Reporter: Timothy Bish
Assignee: Timothy Bish
Fix For: 0.25.0
The existing transfer tag cache suffers from some inefficiencies in both the
tag generation and the management of the tag pool itself. We can reduce the GC
overhead created by the tag cache to near zero by changing the storage
mechanism. The tag generation can be improved by doing the tag encoding
ourselves instead of using the Long toHexString method and then encoding it's
bytes, this greatly improves performance and also reduces GC overhead.
