------------------------------------
Summary: Remove locking on TypedProperties getters
Key: ARTEMIS-5139
URL: https://issues.apache.org/jira/browse/ARTEMIS-5139
Project: ActiveMQ Artemis
Issue Type: Task
Reporter: Josh Byster
Attachments: Screenshot 2024-10-30 at 10.38.54 PM.png
We are noticing a performance degradation when switching to Artemis in places
where we are sensitive on the millisecond level. We have confirmed that moving
to ZGC and having minimal GC pause times cannot explain this spike. Looking at
a flight recording, it does appear we are spending a lot of time blocked on
TypedProperties getters (see screenshot). It seems like we can probably remove
some of the locking here with a concurrent collection or be smarter about it
with a ReadWriteLock, given that it appears we have threads competing for read
calls.
