> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 2.7.0
> Reporter: Francesco Nigro
> Assignee: Francesco Nigro
> Priority: Major
>
> Has been measured that LIvePageCacheImpl operations are a source of

> while using topics, because the page cache is been accessed concurrently by
> several producers to ack transactions while the messages are being appended.
