I tried firing up my messenger-based receivers, each subscribing to 100

only at resident-set size. )
So when I tried to do a total of 1,000,000 addrs on one box, I did
indeed overwhelm my memory. That would come to 115 GB, which
would have been more than double my physical mem.
Please note I did not actually send any messages. A router was running
for these receivers to attach to, but no senders were running.
Does 115 KB per subscribed addr seem fairly reasonable?
No, that seems quite excessive. Can you trace where the memory is actually
coming from?
Just for comparison, a qpid::messaging process with 1000 subscriptions
over AMQP 1.0 uses 48MB on my laptop. A similar process using AMQP 0-10
uses 8MB.
