title: Understanding Chrome Heap Profile
body: <p>I am trying to diagnose an SPA.  I took two snapshots, one right after another, while the app was idle. Here is a snapshot below.  As you can see, the shallow size of these objects is huge.  But I have no idea what they are, or where in the code they come from.  The (compiled code) does not make sense to me, nor do deoptimization_data or relocation_info.</p>
  
  <p>Does anyone know how to use this information to actually track down leaks in a sizable app?</p>
