 You should evaluate, as the blogpost reccommand, the right value of prefetch_size accordingly with the time taken to process each message and your network performance.
 
 With RabbitMqBundle, you can configure that qos_options per consumer like that:

 Here we have a very useful server: it returns random integers to its clients. The callback used to process the request will be the __random\_int\_server__ service. Now let's see how to invoke it from our controllers.
 
 First we have to start the server from the command line:
