Can you explain why you're wasting a lot of bandwidth/CPU time in pub/sub?

  if you're not using multicast in pub sub, you're establishing individual tcp connections between nodes, it's not any different than doing N point to point communications, whereas with multicast, the data is only copied when needed, your data will fan out if that makes sense with your network topology I think if you look at the picture it'll be clear http://en.wikipedia.org/wiki/Multicast http://en.wikipedia.org/wiki/Multicast
