Chances are you will need to do some tuning to support that many
clients connecting to a single broker. Take a look the following pages
on the website:

So first place to start  is:

  http://activemq.apache.org/how-do-i-configure-10s-of-1000s-of-queues-in-a-single-broker-.html
Certainly use nio:// transport - and I'd recommend looking at Kahadb -
http://activemq.apache.org/kahadb.html

with  a 5.3-SNAPSHOT

cheers,
