title: speeding up google closure compiler jar
body: <p>The Google Closure Compiler for JavaScript is quite speedy when I use it online; however, it takes up to 10 seconds to run from the commandline (<code>java -client -jar path/to/closure.jar options...</code>).</p>
  
  <p>Is there any way to reduce this to the same times as the web app (3 seconds max)? I cannot use the web app because my company requires all builds be able to work without an internet connection.</p>
  
  <p>I suspect this is mostly startup time (why I added the <code>-client</code> tag), but I don't know.</p>
