No. The queue is not only buffering, it provides a thread boundary and  
thus decouples the 1:n element from each uf the downstream chains. If  
you don't use the queues, one slow sink could starve the whole  
processing.

The overhead should be relative minimal. The queue will forward the  
buffers as soon as it has some and it gets scheduled.
