(was: Eliminate zeroing of buffers while writing the journal)
> Eliminate zeroing of buffers while writing the ASYNCIO journal
> --------------------------------------------------------------
>
> Key: ARTEMIS-2849
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2849
> Project: ActiveMQ Artemis
> Issue Type: Test
> Components: Broker
> Reporter: Francesco Nigro
> Priority: Major
>
> By default ASYNCIO, NIO and MAPPED journal while using TimedBuffer are
> zeroing the ByteBuffers used to perform the write on the journal: under load
> TimedBuffer can be big enough that zeroing would cost the same as copying the
> actual content into it, hence saving the zeroing is quite beneficial to save
> CPU time and increase IOPS.
