>
> When we have a queue with only pull consumers (prefetch 0), there are a lot
> of necessary work being done trying to dispatch every paged message to every
> consumer. The problem is that most of consumers are full all the time and we
> lose a lot of cpu time trying to traverse all messages. The problem is more
> apparent with large number of paged messages.
