ActiveMQ is highly concurrent; though to really power multiple cpus
you need to have lots of clients doing lots of concurrent sending and
consuming. Also note that out of the box ActiveMQ uses persistent
messaging - which from a single producer thread perspective spends
most of its time waiting for things to be written to disk which is
kinda hard to use up 4 CPUs until you have lots of producers.
