You could use tracing / firehose to generate trace messages with 
timestamps when the broker receives the messages.

http://www.rabbitmq.com/firehose.html
http://hg.rabbitmq.com/rabbitmq-tracing/file/rabbitmq_v3_2_3/README

That would give you some confirmation that the messages are not getting 
delayed in queues somehow.

But I suspect you'll find that the delay is before the broker generates 
the firehose message. So the next step would be to watch the publishing 
connection with Wireshark; that can analyse AMQP frames so you should be 
able to see the messages just before they reach the broker.

I strongly suspect you'll find the problem lies in your client 
application though...

Cheers, Simon
