The JBM 2 are preliminary numbers. I have been trying recently on my developer branch and I can already get numbers 30 or 40 % higher on persistent messages.

You will have some information on the documentation. On JBM 1.4 the load is redirect to the next node on the cluster. Persistent Messages are stored on a shared database.

  | 
  | 

We support Message Consumers.. yes. I'm not 100% sure what you meant on this question.

  | 
  | 

You can configure JBM accordingly to deal with slow consumers. So.. that's a yes.

JBM 1.4 supports a shared db mechanism. On JBM 2 we are working on providing a journal which is pretty fast.
