We have made some improvements to make the management plug-in more 
responsive when the server is under load, particularly when there are 
lots of connections or queues. These will appear in a future release.

As Emile noted in the other thread, you probably only need one virtual host.

Still, the management plug-in should cope with that many vhosts.

When you say that there are "0 messages" do you mean that there are zero 
message in the queues or that there are zero messages flowing in and out 
of the system? It's the latter which generates load.
