title: Increase memory for ant
body: <p>I have an issue about memory usage.
  I had 8 GB of RAM and I had my ant settings like this:</p>
  
  <pre><code>set ANT_OPTS=-Xmx512m -XX:MaxPermSize=2G
  </code></pre>
  
  <p>Now, I have installed 16 GB of RAM but when I run an ant clean all, this take the same time to compile.</p>
  
  <p>How I have to set the options to increase memory and speed? I have Windows 7 64bit and 16 GB RAM. I use Eclipse, but I run ant clean all and server Tomcat from the cmd. </p>
