Hi Mike,
If you are talking about non-persistent messages for queues, then yes,
the performance should be much better. If you are talking about topics
- that is another story. My application was primarily queue-based, so I
wasn't concerned with the performance of topics.
Cheers,
David

Hi David,
I'm new to ActiveMQ and unfamiliar with the code (albeit w/experience in
JMS), so forgive me if this is a silly question: do the performance
issues/fixes discussed affect non-durable subscriptions (w/non-persistent
messages) as well?

Rob and I did some performance enhancements with queues so that a
Queue.send() call was decoupled from the dispatch processing. In the
past, depending on the state of the consumers, a Queue.send() call could
take a significant amount of time. We changed it so that a single
thread was responsible for dispatching messages, which avoided a lot of
lock contention. It also meant a Queue.send() returned as quickly as
possible.
I imagine a similar change could be done for Topics, since from what I
can tell, a Topic.send() call currently does its dispatch processing in
the same call.
Cheers,
David
