title: Reasons for seeing high "% Time in GC" in Perf Mon
body: <p>While monitoring our application in Perf Mon I noticed that the % of Time In GC is anywhere from 20 - 60% while our application is performing a long running process (varies between 30 seconds to 1.5 minutes).  This seems a bit excessive to me.  This raises two important questions.</p>
  <ol>
  <li>Am I correct that this excessive?</li>
  <li>How can I figure out why route causes GC spikes?</li>
  </ol>
