Subject [jira] [Commented] (AMQ-4701) NIO transport performance for ActiveMQ
Date Wed, 18 Sep 2013 10:37:52 GMT


Anuj Khandelwal commented on AMQ-4701:

Hi Timothy,
 I have also tested NIO transport with large number of clients, please find below details
for test performance results:

USING 20 producers

Clients            No. of threads before running producer   No. of threads after running producers(~20)

STOMP (PYTHON producer)               63                                 72
STOMP +NIO(PYTHON producer)           67                                 82
TCP(JAVA producer)                    58                                 86
NIO(JAVA producer)                    58                                 87

Transport Connector in broker configuration is :

            <amq:transportConnector name="amqBrokerTcpTransport" 
                                    uri="tcp://" />

            <amq:transportConnector name="amqBrokerNioTransport" 
                                    uri="nio://" />

            <amq:transportConnector name="amqBrokerStompTransport" 
                                    uri="stomp://" />

            <amq:transportConnector name="amqBrokerStompNioTransport" 
                                    uri="stomp+nio://" />

> Hi,
> I am using 5.8.0 version of ActiveMQ. I am trying to use NIO to improve  performance
and scalability of my ActiveMQ broker but it is not working well. I was expecting that it
should reduce number of threads but I have not observed any changes in number of threads.
It is even reducing the throughput. 
> I have made changes in broker's configuration file as specified
> Can somebody help me here.
> Thanks,
> Anuj
