Hi ,
i am trying to use qpid because of persistence queues .i am able
to achieve this by using messaging API and client API .but in
both library's i am facing same problem like when i am sending the messages
by using synchronous session it is giving through put as one only.For this
problem i am suspecting some sleep is there in synchronous session sending
but some one given me replay as there is no that type of thing in cpp, and
he asked me to run following command i am pasting you the result also.
./qpid-perftest --sync-publish=true --durable=true --count=10
Processing 1 messages from qpid-perftest_sub_ready . done.
Sending start 1 times to qpid-perftest_pub_start
Processing 1 messages from qpid-perftest_pub_done .
done.

with this command also it is giving maximum 1 or 2 throughput . is there
any method to increase the throughput .with the above command i got clarity
there is no mistake in my coding i think in some where i am missing
to achieve more throughput if any body using synchronous with durable
messages and achieving more throughput please help me.
As I mentioned last time, that seems unusually low (I get 1000 times
more messages per sec even on my laptop) and there would appear to be
something odd with your system. Try running qpid-perftest in a few
different configurations to see if that gives any hints as to where the
problem lies:
(a) --sync-publish=false --durable=true
(b) --sync-publish=true --durable=false
(c) --sync-publish=false --durable=false
(d) --tcp-nodelay --sync-publish=true --durable=true (in this case, also
set --tcp-nodelay on the broker)
Make sure you run for more than 10 messages though as such a low run
will skew your results.
