  cbq has the trait of coupling bandwidth with delay.  if you want
  to ensure less latency, you need more bandwidth.

  cbq is great for when you want to guarantee that each client
  can receive equal bandwidth when there is much traffic; or also
  to gracefully deal with situations where only one client is active,
  so it receives the benefit of borrowing.

  but for you, you want to be able to create a queue where
  you are not allocating to the queue a high overall bandwidth,
  but it has the property of a very low latency, so this is 
  what hfsc can provide you.
