Subject Slow producing of messages, expected behaviour?
Date Thu, 01 Jul 2010 12:06:39 GMT

I'm trying to improve the performance of our backend and is currently as
benchmark using a use case that takes about ~800 ms to execute and produces
40 JMS messages that are put on a queue (BytesMessage). Each message is a
few kb.

If I dummy out the JMS delivery, the same use case takes about 40 ms to
finish, meaning that it spends most of it time waiting for messages to get
accepted by ActiveMQ. I have also verified this by profiling.

The delivery is performed using a JmsTemplate, configured with a pooled
connection factory.

Without going into more detail, is this expected behavior, around 20 ms or
so for a message to get delivered, or am I missing something obvious that
could speed this up.

I'm currently looking at making architectural changes that would mean that
the actual sending of the messages don't need to be synchronized with the
use case, but it would require some redesigning and I would rather see that
I would be able to use the current "simple" approach with messages being
sent as they are produced by the application.

Any input or help would be greatly appreciated. Any more info I can provide?
