Hard to say. We're running about 1.5 million connections per day
(don't have a count on number of actual messages successfully received
since a huge majority of the connections are rejected for one reason
or another), but on the other hand we load balance between 4 servers
that also run other apps.
I'd guess that it would definitely be an issue if you are running the
databases on a single disk store with that kind of load. Ram disk
would definitely be a requirement I would venture, and even then, the
locking load might still be significant.
