Subject Re: Slow message dispatch
Date Tue, 02 Sep 2014 18:32:16 GMT
Broker is non-persistent. I am sending very small messages and the measure
is only between when I send the message and at the other end when I receive
the message. Consumers and producers are not busy at this point.

I am not re-creating sessions, I am using thread local and I am caching
sessions. I am also not re-creating temp queues, that also gets cached
using thread local.

Should I profile activemq? Is there an easy tutorial on how to profile
activemq?
