Work Description: qihongxu commented on issue #2494: ARTEMIS-2224 Reduce
contention on LivePageCacheImpl
URL: https://github.com/apache/activemq-artemis/pull/2494#issuecomment-454686710
> 900M of page size and very small messages are not such a common use case
TBH
Agreed. Use this case just to make it stay at livePageCache longer. In
production we use default 10M page size, which means that under high
concurrency it's not easy for livePageCache to be read&write at the same time.
In conclusion this patch works fine as described and performance benefits
from it:)

> 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.
