Hi again,

When I changed the connection from blocking to non-blocking (using select
connection method) my throughput has increased hugely.
Also correctly configured publisher confirm as per yesterday's suggestions.

I am yet to try different things but from the initial tests on high end
server now I can see I can publish 8000 msg/Sec with single publisher and
no consumer.
On my macbook I get 1800 msg/sec throughput with single producer and single

Thank you all again. It was very helpful for my work. I will not try to
simulate multiple producers/consumers using this improvements and see what
throughout I get.
