Creating a single connection and having ~25 channels will be perfectly 

I recommend using QueueingConsumer for each of the consumers on these 
channels to prevent any possible deadlock problems.

Setting channel.basicQos(1) will mean that your consumers get 
approximately fair distribution of the work, but you should ensure that 
you are using autoAck=false when setting up the consumer otherwise QoS 
settings are ignored.
