WBIMB is designed to be a high performance pub/sub broker.
I would be surprised if you would notice any performance hits on most hardware with less than a few thousand subscriptions.
But it depends a lot on the size of the published messages, as well as the complexity of the subscription requests - are they all topic based, or are some content based as well?
The Performance support packs should have some numbers you can look at. _________________ I am *not* the model of the modern major general.
