title: Redis CPU spike
body: <p>The problem is described and answered here: <a href="https://groups.google.com/forum/#!topic/redis-db/egyA1xvhGfo" rel="nofollow">https://groups.google.com/forum/#!topic/redis-db/egyA1xvhGfo</a></p>
  
  <p>Unfortunately I do not fully understand the answer. </p>
  
  <p>My concerns are if redis takes up 100% CPU every 5 minutes and if my server only has a single CPU (i.e. staging) would that mean it will freeze my httpd process every 5 minutes?</p>
  
  <p>Would this not be of a concern if my server has multiple CPUs? </p>
