> Can you help us Justin, to understand why ?? Not until you get me something more concrete like a reproducible test-case, output from a profiler indicating where the hot-spot is, or even a series of thread dumps from when CPU utilization is high.

We just made another test , just connecting, without subscribing, in order to check if the problem is the authorization procedure... and we discovered that this step doesn't occupy a lot of cpu (never reached 5% of usage). So we can say that the "heavy" step is the subscription procedure made after connection. For each client , we made a subscription to 50 topics (different for each clients). In our test we subscribed 2000 clients (so, 50x2000 = 100K topics). During this period (that has requested 1h), the CPU of broker during subscriptions was ever near 100% of usage! Can you help us Justin, to understand why ?? Thanks. -- View this message in context: http://activemq.2283324.n4.nabble.com/Apache-Artemis-Stress-test-time-tp4723999p4724785.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
