Reporter: Nicolas CASAUX
Hello,
I'm using Artemis with 5000 Stomp connections (and 5000 sessions and 5000
queues), all subscribed to the same queue with multicast routing type (topic).
Everything is running on my local computer.
When I use the "Connections" tab from the "Artemis" panel in the web console, I
observe this:
* the "Connections" info are displayed after more than 90 seconds
* the CPU of Artemis is stuck at 15% for more than 2 minutes:
I don't have this behaviour when I use the "Sessions" tab or the "Queues" tab
(which display the 5000 items using paging). They are almost instantly
displayed.
