Francesco Nigro commented on ARTEMIS-3335:
------------------------------------------
It worth to check https://github.com/hazelcast/hazelcast/pull/17435 becuse
using OpenHFT doesn't seem an option for some users.
> Improve Artemis Thread affinity
> -------------------------------
>
> Key: ARTEMIS-3335
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3335
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker, Configuration
> Reporter: Francesco Nigro
> Priority: Major
>
> https://issues.apache.org/jira/browse/ARTEMIS-3303,
> https://issues.apache.org/jira/browse/ARTEMIS-3289 and
> https://issues.apache.org/jira/browse/ARTEMIS-3045 shown how much it worth to
> improve the mechanical sympathy of broker, regardless specific hardware.
> A well tuned broker can easily improve performance and helping users exposing
> the right hooks to perform programmatically and/or automatically such tuning
> is a nice addition and traction for high-performance scenarios.
> Thread affinity plays a big role on this and there are already Apache
> libraries that could help setting it for specific thread pools in the broker
> (global thread pool, I/O thread pool, netty acceptor thread pools, netty
> connector thread pools, timed buffer thread, ASYNCIO background thread etc
> etc) eg https://github.com/OpenHFT/Java-Thread-Affinity
> There are other project that employ an ad-hoc affinity strategy eg Hazelcast,
> failback to OpenHFT one in case ad-hoc ones cannot be used (see
> https://github.com/hazelcast/hazelcast/commit/a7e7defde2086b20a3af93e6d59ff4fadfd06ae4)
