title: reduce memory that tomcat is using
body: <p>I am using tomcat for my web application. I am starting server from services. I have this configuration:<br>
  -Xms256m;-Xmx512m;-XX:PermSize=256m;-XX:MaxPermSize=512M  </p>
  
  <p>When I change this configuration and restart service and check in task manager, how much memory it is using, it is showing that it is using the same memory every time.  </p>
  
  <p>Note: I am using tomcat 8 on 64 bit windows machine. </p>
