Michael Andre Pearce (IG) commented on ARTEMIS-994:
---------------------------------------------------
I'm not in work this week, so dont have access to full server test rig. But
doing very basic tests using the broker in non persistent mode and using cli
produce/consumer tools (running both sets 10 times and taking the last run)
These are the early results i see simply by switching to epoll, on the same
machine.
NIO:
<acceptor

./artemis consumer --message-count 100000
--url=tcp://localhost:61616?useEpoll=false > consumer.log &
./artemis producer --message-count 100000

> Support Netty Native Epoll on Linux
> -----------------------------------
>
> Key: ARTEMIS-994
> URL: https://issues.apache.org/jira/browse/ARTEMIS-994
> Project: ActiveMQ Artemis
> Issue Type: New Feature
> Components: Broker
> Affects Versions: 1.5.3, 2.0.0
> Reporter: Michael Andre Pearce (IG)
>
> Netty has support for native epoll, this is available only on linux systems.
> This is more performant.
> http://netty.io/wiki/native-transports.html
> This is inline with supporting asyncio with libaio using such native feature
> to bring perfomance benefits to artemis.
