title: Improve gradle startup time with groovyserv or nailgun or what
body: <p>I'm trying to improve the startup time of Gradle.  The expererimental <code>--daemon</code> switch doesn't seem to really speed it up.  So I'm thinking to use some server process independent of gradle, and make gradle connect to it.  The options I found so far are</p>
  
  <ul>
  <li><a href="http://www.martiansoftware.com/nailgun/" rel="nofollow">nailgun</a> to invoke java</li>
  <li><a href="http://kobo.github.com/groovyserv/index.html" rel="nofollow">GroovyServ</a> to invoke a groovy script</li>
  </ul>
  
  <p>Since gradle is started by a shell script, it takes some tweaking.  My question is: has anyone used the above options to start gradle?  Or if you have successfully used another option, what's that?</p>
