How long is a piece of string? Depends what you want to do, doesn't it?

This is a meaningless question, because a queue runner only ever
launches 1 delivery process at a time. I think you are perhaps confused
about remote_max_parallel. That controls the number of (sub)processes
that a single delivery process launches when it has multiple remote
deliveries to do. If you only ever have one recipient per message (as I
seem to recall you do) you won't see any difference whatever you set
remote_max_parallel to.
