1. Is there any performance matrix of durable queues with message size and os

I would like to compare my test results against what is in actual
production?
How many message per seconds should I expect for one broker for 1024
bytes message sent to a durable queue?
Will clustering reduces the broker's throughput and if yes by how much?
I'm not aware of any such matrix - and clearly if such a thing existed
it would be "relative" I guess that it's stating the obvious that it
would depend hugely on your set up.
One thing worth playing with is qpid-perftest which lives in the
cpp/tests directory. Note that this is really a broker load test so it
doesn't represent what a *real* client might do (for example it
generally creates one message outside the critical path and continually
sends that in the loop), but it'll allow you to get a really good
picture of what you need to do with your broker/network/client topology
to get maximum performance.
2. It seems that No-Persistent Queue without Store Module and Topic should
have same throughput. However, I see the queues that are not
durable/non-persistence messages have worse message rate per second than
sending the messages to the topic --
Is this correct does any one can explain this?
3. Does JMS client or C++ Client improve the Broker's overall message
processing or is it indifferent?
Thanks for any information on this.
Go on, have a guess :-)
The Java JMS client is definitely quite a lot slower, though to be fair
it still rocks compared to any other JMS provider I've come across. In
my more obtuse moments I keep getting tempted to write a JMS wrapper
around a SWIG binding to the c++ qpid::messaging API to do a back to
back comparison :-D
