title: Terracotta Performance and Tips
body: <p>I am just learning how to use Terracotta after discovering it about a month ago.  It is a very cool technology.</p>
  
  <p>Basically what I am trying to do:</p>
  
  <p>My root (System of Record) is a ConcurrentHashMap.</p>
  
  <p>The main Instrumented Class is a "JavaBean" with 30 or so fields that I want to exist in the HashMap.</p>
  
  <p>There will be about 20000 of these JavaBeans that exist in the Hashmap.  </p>
  
  <p>Each bean has (at least) 5 fields that will be updated every 5 seconds.</p>
  
  <p>(The reason I am using Terracotta for this is because these JavaBeans need to be accessible across JVMs and nodes.)</p>
  
  <p>Anyone with more experience than me with TC have any tips?  Performance is key.</p>
  
  <p>Any examples other similar applications?</p>
