ARTEMIS-4543 Reverting to previous semantic on MappedSequentialFile
> Journal Sync in NIO not scalling
> --------------------------------
>
> Key: ARTEMIS-4543
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4543
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Clebert Suconic
> Assignee: Clebert Suconic
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> when using journal NIO, and a sync is requested, no further syncs are able to
> come through until the first write is flushed.
> This is because TimedBuffer will hold a lock while the flush is being done,
> and a file.sync is being called.
> To improve this, the sync should be done away from the lock.
