title: How to understand CPU and memory consumption in xcode debug
body: <p>In Xcode 5, there's a new debug panel that shows the CPU and memory consumption in % and MB respectively. How do we make use of this? Is there a CPU % threshold I should try to stay below? I sometimes see my apps goes to 100% or over.. does that mean I am doing too much processing in my app and should try to optimize?</p>
  
  <p>Any tips?</p>
