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 name="artemis">tcp://0.0.0.0:61616?useEpoll=false;tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;protocols=CORE,AMQP,STOMP,HORNETQ,MQTT,OPENWIRE</acceptor>


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

>                 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.
