Slow performance in JBoss 5.1.0 GA

[atan20]

I was wondering if someone could help me determine why my HornetQ instance which is integrated with JBoss 5.1.0 GA, is running considerably slower than HornetQ when it is running standalone?

I am running the HornetQ perf tests under "examples/jms/perf" in the HornetQ package with durable set to true using one queue, one producer and one consumer.

When I run the test with the standalone server I am receiving a throughput of 433 messages/second. However, when I point the perf test to use a Queue on my JBoss installation with HornetQ the throughput drops to 233 messages/second.

Our JBoss HornetQ instance is using AIO and I have applied the following JVM tuning to match the standalone server:

- -XX:+AggressiveOpts

- -XX:+UseFastAccessorMethods

- Increased -Xms and -Xmx settings from 512 to 2048 and ensured they were set to the same value

- -XX:+UseParallelGC

- disabled security in hornetq-configuration.xml

Below are my settings from perf.properties:

num-messages=150000

num-warmup-messages=10000

message-size=1024

durable=true

transacted=false

batch-size=1

drain-queue=false

throttle-rate=-1

durable-message-id=true

disable-message-timestamp=true

The JBoss server is dedicated to messaging and the machine has ample CPU and memory available for the test applications and JBoss.

Thanks.

It has to be environmental. I don't think there would be anything that would affect performance. it's the same thing basically.

Have you checked the place where data is placed? No mounts.. nothing different?

[atan20]

I have JBoss and HornetQ on the same partition on the disc and there are no mounts on that server.

Could there be extra transaction overheads when running in JBoss by default? In both cases I am using the non-XA connections so I don't believe its a quality of service overhead issue.

there will be if your using MDB's, otherwise the only other overheads are the other jboss services.
