Subject Re: Apache Artemis - Stress-test time
Date Mon, 10 Apr 2017 14:56:19 GMT
Hello, 
I'm a colleague of Francesco. 
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.
