title: Increasing Tomcat Heap Size
body: <p>I'm trying to increase the heap size of tomcat (so i can optimize GeoServer performance), what i did is:</p>
  
  <ul>
  <li>Change the JAVA_OPTS values in tomcat default file to be:</li>
  </ul>
  
  <blockquote>
    <p>JAVA_OPTS="-Djava.awt.headless=true –Xmx3072m -XX:MaxPermSize=512m"</p>
  </blockquote>
  
  <ul>
  <li>Restart tomcat</li>
  </ul>
  
  <p>When I checked JVM values is shows:</p>
  
  <blockquote>
    <p>Free memory: 440.33 MB Total memory: 495.06 MB Max memory: 2969.62 MB</p>
  </blockquote>
  
  <p>I'm not sure whether this good or not. </p>
