Justin, Appreciate your reply. Your insight is greatly appreciated and invaluable.
If you can provide more details on this, then I would appreciate it. I can search the archives for it as well. I am guessing there is some command line equivalent to represent the tree. What we have is several devices that have JMS clients that communicate with the broker on topics and durable queues. By “several devices” I mean maybe 100s or 1000s.

That said, there certainly are limits, the size of your heap probably being the most important. Every address and queue carry with it some memory overhead including the objects themselves but also related objects like JMX MBeans which enable management. The current management console will struggle by default with a huge number of addresses and/or queues due to the way the "tree" view works (i.e. refreshing the whole view on a regular basis). This is the main reason we removed this view in the new console [1]. That said, the console can be configured in such a way as to mitigate some of these problems. I can provide more details on that if necessary although it's been covered on this list a few times already. Regarding scalability...the broker was written with scalability in mind, but everything breaks down at some point. I'm interested to hear about your experiences if you go down this route especially regarding bottlenecks that you may find for your specific use-case. Keep us in the loop!
