There is a CachingConnectionFactory in the Spring .NET APIs:

http://springframework.net/docs/1.3.0/api/net-2.0/html/topic17141.html

I believe that the implementation in Spring .NET is nearly the same as
the one in the Spring Java APIs. But I'm not a Windows/.NET type so
I've CC'd Mark Pollack who created and maintains Spring .NET.

Various aspects of ActiveMQ can be monitored through JMX and jconsole
will provide resource utilization monitoring. The best thing to do is
test it in your environment (i.e., on your machines with your
destinations, with your anticipated load, etc.) and watch the broker
memory usage. The memory available to the broker can be adjusted via
the <systemUsage> element in the activemq.xml. More info about it is
available here:
