[jira] [Created] (ARTEMIS-2224) Reduce contention on LivePageCacheImpl

Francesco Nigro created ARTEMIS-2224:
----------------------------------------

             Summary: Reduce contention on LivePageCacheImpl
                 Key: ARTEMIS-2224
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2224
             Project: ActiveMQ Artemis
          Issue Type: Improvement
          Components: Broker
    Affects Versions: 2.7.0
            Reporter: Francesco Nigro
            Assignee: Francesco Nigro


Has been measured that LIvePageCacheImpl operations are a source of contention on producer side while paging. 
This contention decrease the scalability of the broker in an evident way while using topics, because the page cache is been accessed concurrently by several producers to ack transactions while the messages are being appended.
