Francesco Nigro commented on ARTEMIS-3131:
------------------------------------------
This could be implemented by sharing the event loop group between acceptors:
see

> NettyAcceptors and NettyConnectors aren't sharing EventLoopGroups

> Key: ARTEMIS-3131
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3131
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 2.17.0
> Reporter: Francesco Nigro
> Assignee: Francesco Nigro
> Priority: Major
>
> Currently a broker started with N acceptors creates N EventLoopGroups ie N x
> (3 x cores) different event loops/threads.
> Same is happening with NettyConnectors.
> Ideally both should share any existing EventLoopGroup (using ref counting to
> shutdown the shared one) to save creating too many threads and waste
> unnecessary resources.
