Interesting - ok, yes, that certainly is sufficiently high as to be
beyond the capability of rabbit on non-exotic hardware with acks turned
on. Ultimately you'll find that a single queue will become your
bottleneck as queues are individually single-threaded. Thus you might
find that you can scale better by having multiple queues for the same
purpose and spreading your publishes across them. Of course, you need to
be careful about which ordering guarantees you may start to lose...
