How Activemq handles a lot of undelivered messages to a durable
subscribers
If I have several durable subscribers of a topic and one of them is down,
I would like to know if a lot of undelivered messages to that durable
subscriber will have big performance impact on the delivery of the messages
to other active subscribers.
Thanks!

It will have some impact (if nothing else it means less cache hits
when dispatching messages so there may be additional swapping from
persistent store to RAM) - the actual impact depends on lots of
factors

So I'd recommend trying it out on your hardware to see.
