Hey Tim, thanks for the feedback.
If the waiting time on the consumer side is included in enqueue time I'm
wondering what the measurement points are for dequeue time.
Thanks

What Chris described is how to load the existing messages into your new
broker. That has always seemed clunky to me because there is no way to
store messages in multiple OpenWire formats (which means your new broker's
store is stuck forever on the old broker's OpenWire version), so the option

Great, I'm glad to hear that 5.14.5 works for you. Thanks for letting us

Justin,
Thanks for linking the design document for the benchmark test I will need
to take a look and see how what the test is for the results to come up with
that kind of speed.
Based on my own experience using several types of brokers a typical message

I totally agree. Just be good to somehow quantify and highlight that hard work
and how much the project has improved from what was compared to today. And I
guess next year again.
I guess if running that spec is too expensive re resource it's not worth it.

Can you please describe what you see in JConsole that tells you that the
messages are lost? (And can you please define the word "lost" as you're
using it here? Do you mean that they are acked - but not by your code - or
that they end up in the DLQ or something else?)

@Michael Pearce: The native module on Artemis is totally rewritten...
hornetq libaio used a lot of malloc. Artemis is only calling malloc
once and reusing them on a pool... a lot less locking happening...
just the libaio is better..
For instance.. an issue that you had with 512 bytes blocks recen
I'm not aware of any SpecJMS results using any branch of Artemis. It'd be nice
to have, but one basically has to set up a lab with dedicated hardware, set up
the software, run it, etc. It's a fairly involved process from what I
understand.

As you noted, with all the changes since hornetq became artemis, is there an
updated run of that same JMSspec but on 2.x artemis?
It be great if there was. Just to see.

Couple of things...
1) I agree 100% that comparing Kafka to message brokers like ActiveMQ is like
comparing apples to oranges. They are really quite different.
2) My point wasn't necessarily to compare Artemis' performance with Kafka.
My reply was simply in response to your assertion that,

For what it's worth, HornetQ (upon which Artemis is based) achieved over 8
million messages per second on SpecJMS [1]. I would expect Artemis'
performance to be comparable (or bette
To be clear, there's really only 1 addressing model, but that model supports
lots of different use-cases. It's very flexible and supports traditional
pub-sub and point-to-point (as you noted).
The benefit of supporting multiple "anycast" queues on a single address is
simply that if you need th
Each message your producer publishes has to have the persistent flag set,
otherwise the (non-persistent) message will be stored in the memory store.
Are you setting that flag when you publish your messages?

Artemis is intended to be the follow on to ActiveMQ 5.x. It is currently
being actively developed to add new features to it with the goal that the
useful features from ActiveMQ will also be added to Artemis. Most of the
development effort is being done there and ActiveMQ 5.x is basically in

What is the difference between Artemis and current ActiveMQ versions? When
should one be preferred over another? Is there any difference between
features?
Artemis docs say it has outstanding performance - should this be preferred
over ActiveMQ? How stable Artemis is in production environments?

A reproducer is the best way for us to help diagnose/fix the issue.
Failing that, are you able to profile the broker to see which objects are
getting leaked?
There are a couple of MQTT specific things to check such as retained

You can't compare Kafka to a JMS type message broker. Kafka is completely
different.
Kafka is a system that scales horizontally and is essentially a big
write-ahead log and breaks up the topics into partitions across many
servers so they can be scanned concurrently. This allows insane message
