svn commit: r476299 - /incubator/activemq/trunk/activemq-core/src/test/java/org/apache/activemq/perf/QueueConnectionMemoryTest.java

[ra...@apache.org]

Author: rajdavies
Date: Fri Nov 17 12:23:54 2006
New Revision: 476299

URL: http://svn.apache.org/viewvc?view=rev&rev=476299
Log:
A simple test to allow profiler to get an idea of how much memory is allocated per
temporary Queue. It appears that the ConsumerAdvisory - one for each Connection, holds
a copy of every temporary Queue in the system.

I don't think this is a big issue - unless - as in this case - all the connections and the
broker are in the same jvm.
