title: activemq performance gotchas and precautions
body: <p>I am going to use ActiveMQ for the first time in one of my projects (topics for durable messages). I have read that durable messages enforce a limit to the scale of number of messages per second. What are the other factors that I should be aware of (e.g. slow consumers) that puts a limit to the scale and performance characteristics of activemq and what metrics should be closely monitored and what are the values at which all hell breaks lose. </p>
  
  <p>I don't expect to be pushing more than a thousand events per second in ActiveMQ for now.</p>
