title: Why is my Pentaho server running slow, on Linux?
body: <p>I am using Pentaho 4.8 and this is the configuration in my <code>start-pentaho.sh</code></p>
  
  <pre><code>export CATALINA_OPTS="-Xms256m -Xmx1024m -XX:MaxPermSize=256m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
  </code></pre>
  
  <p>Can anybody please explain what these parameters mean ???</p>
  
  <pre><code>-Xms256m 
  -Xmx1024m 
  -XX:MaxPermSize=256m
  </code></pre>
  
  <p>I did not find any particular reason, why my server on my Linux machine is responding very slow. I thought may be increasing the size here might help , but I don't want to change until I understand the parameters, if anybody have any suggestion for increasing my server speed, then please help me</p>
