Hi Adel,
I used a benchmarking tool called ebench
(https://github.com/EnMasseProject/enmasse-bench) that connects a client
(actually 2, a sender and a receiver) to an AMQP endpoint.
Before sending each message, it puts a message tag and timestamp into a
map, and when it is settled by the receiver, it records the elapsed time
for that message and increases 'sentMessages'. Once the test has
finished, it can produce various statistics such as throughput by
calculating sentMessages/totalTime and also average latencies and
percentiles.
I can't comment on JMS performance, as I have not used it yet. The
benchmark tool uses qpid-proton reactor java API. Anyway, I'm not sure
my numbers are comparable to yours. I just wanted to point out that
dispatch router should be able to process that amount of messages just
fine on standard hardware.

And how do you measure your throughput?

Hello Ulf,
I am sending messages with a byte array of 100 bytes and I am using Berkley DB
as a message store (which should be slower than having memory only message
store, no?)
With 1 consumer, 1 producer and no broker, I am at 33k msgs/sec if they are all on the same machine
and I have set "jms.forceAsyncSend=true" on the producer and
"jms.sendAcksAsync=true" for the consumer.
Are you using other options to get 190k? Do you think JMS might be a
bottleneck? Or something else in my config/test?
JMS client 0.9.0
Qpid Java Broker 6.0.1
Dispatcher 0.6.0

Hi,
Excuse me if this was already mentioned somewhere, but what is the size
of the messages you are sending ?
FWIW, I'm able to get around 30-40k msgs/sec sustained with 1 producer,
1 consumer, 1 dispatch (4 worker threads) and 1 broker (activemq-5). The
sender sends unsettled messages as fast as it can using qpid-proton
reactor API which is sending async up to the window limit.
With no broker involved, I'm getting ~190k msgs/sec.
All of these numbers are from my 8 core laptop. Message size is 128 bytes.
I don't know the dispatcher that well, but I think it should be able to
handle data from each connector just fine given the numbers I have seen.

Hello again,
As requested, I added a 2nd connector and the appropriate autoLinks on the same
host/port but with a different name. It seems to have resolved the issue.
1 Broker, 1 Dispatcher, 3 producers, 0 consumers, 1 connectors --> 5000 msg/s.
1 Broker, 1 Dispatcher, 3 producers, 0 consumers, 2 connectors --> 6600 msg/s.
1 Broker, 1 Dispatcher, 4 producers, 0 consumers, 2 connectors --> 7700 msg/s.
I think this confirms the problem is due to the fact a single connection is
being shared by all clients (consumers/producers) and that having a sort of
pool of connections or a connection per workerThread is a solution to consider.
What do you think?
I added a 3rd connector to see if it changes anything but it
didn't. Do you think this is maybe because the dispatcher is not able
to process fast enough and saturate the 2 connectors?
1 Broker, 1 Dispatcher, 4 producers, 0 consumers, 3 connectors --> 7700 msg/s.

Sorry for the typo. Indeed, it was with 3 producers. I used 4 and 8
workerThread but there wasn't a difference.
We want to benchmark in the worst case scenarios actually to see what is the
minimum we can guarantee. This is why we are using synchronous sending. In the
future, we will also benchmark with full SSL/SASL to see what impact it has on
the performance.

How about the tests we did with consumer/producers connected directly to the
dispatcher without any broker where we had 16 000 msg/s with 4 producers. Is it
also a very low value given that there is no persistence or storing here? It
was also synchronous sending.
The rate is low because it is synchronous. One messages is sent to the
consumer who acknowledges it, the acknowledgement is then conveyed back
to the sender who then can send the next message.
The rate for a single producer through the router was 6,000 per second.
That works out as a roundtrip time of 167 microsecs or so. In your
table, the 16,000 rate was listed as being for 3 producers. Based on the
rate of a single producer, the best you could hope for there is 3 *
6,000 i.e 18,000. (How many worker threads did you have on the router
for that case?)
