title: Intellij IDEA freezes up, even when editing a .txt file
body: <p>When I return to intellij, sometimes just to edit an already open .txt file, Intellij would freeze and I get pissed at waiting for 3-4 seconds. </p>
  
  <p>Sometimes, in Java files this happens all the time. And I would have to restart Intellij. Autocompletion is sometimes a ****.</p>
  
  <p>I have a super computer, ala NSA, no just kidding, but it is a powerful beast, and Intellij properties have been altered: </p>
  
  <pre><code>-server
  -Xms2048m
  -Xmx4096m
  -XX:MaxPermSize=2048m
  -XX:ReservedCodeCacheSize=2048m
  -ea
  -Dsun.io.useCanonCaches=false
  -Djava.net.preferIPv4Stack=true
  -Djsse.enableSNIExtension=false
  -XX:+UseCodeCacheFlushing
  -XX:+UseConcMarkSweepGC
  -XX:SoftRefLRUPolicyMSPerMB=200
  -Dawt.useSystemAAFontSettings=lcd
  </code></pre>
  
  <p>Various plugins have been disabled, including hg4xxx. </p>
  
  <p>What is the dealio? I am on Intellij 13</p>
