[rabbitmq-discuss] RabbitMQ QUEUE MESSAGES

Hi I have question about buffering messages in RabbitMQ server. When my
producer try to send more messages than consumer could read than messages
should be queued. I suppose that all messages that producer want to send to
messages broker would be on the queues, but after some time there is flow
control fired and my producer couldn't send as much messages as I want to.
How could I turn off that feature?

I desribe my workaround for that:
I wrote special module to queue messages. I see that if RabbitMQ doesn't
have messages on its queues it works fast. So if my producer would want to
send more messages than consumer can read, than my module store them in its
memory and publish the messages to message broker  when consumer's queue is

In normal situation it should look like this 

 Producer -> RabbitMQ  -> Consumer

but in that scenario producer's sending is slowed down by the RabbitMQ flow

My scenario is 
  Producer -> RabbitMQ -> Buffer Module -> RabbitMQ -> Consumer

because RabbitMQ message broker is as I see only to route the messages not
to store them.

I changed also watermark to 100 and disk_free_limit is set to 0.

Best Regards,
