----------------------------------------
Summary: ASYNCIO blocked poll can spin wait I/O completion
Key: ARTEMIS-3361
URL: https://issues.apache.org/jira/browse/ARTEMIS-3361
Project: ActiveMQ Artemis
Issue Type: New Feature
Reporter: Francesco Nigro
Assignee: Francesco Nigro
Follow-up of https://issues.apache.org/jira/browse/ARTEMIS-1977: thanks the
recent changes on Linux kernel, introducing NVMe polling-mode (see
https://patchwork.kernel.org/project/linux-block/patch/1446830423-25027-5-git-send-email-ax...@fb.com/)
to reduce the amount of IRQs (and context switches) with super-fast NVMe disk,
this issue can save any blocking to happen during ASYNCIO poll (if not for
fdatasync, that can be improved with NVMe polling mode too) setting the
appropriate journal configuration.
