title: WebStorm uses 100% CPU
body: <p>I use WebStorm 11 and developing in Angular2.
  The ng serve is working on background from the cmd and the CPU is on 1% work.</p>
  
  <p>When the WebStorm is opening, the CPU jump to 30%-60% and when he start indexing it goes to 100% until the WebStorm crushes.</p>
  
  <ul>
  <li>I have Intel(R) Core(TM) i503210M CPU @ 2.50GHz 2.50GHz and 8G RAM (I
  don't have RAM problem). </li>
  <li>I excluded <code>dist</code> and <code>node_modules</code> folders but
  the indexing still takes too long.</li>
  </ul>
  
  <p>WebStorm.exe.vmoptions:</p>
  
  <pre><code>-server
  -Xms128m
  -Xmx1012m
  -XX:MaxPermSize=512m
  -XX:ReservedCodeCacheSize=512m
  -XX:+UseConcMarkSweepGC
  -XX:SoftRefLRUPolicyMSPerMB=50
  -ea
  -Dsun.io.useCanonCaches=false
  -Djava.net.preferIPv4Stack=true
  -XX:+HeapDumpOnOutOfMemoryError
  -XX:-OmitStackTraceInFastThrow
  </code></pre>
  
  <ol>
  <li>What does the indexing do? Can I turn it off?</li>
  <li>What is the best way to configure this for small projects?</li>
  </ol>
