title: How to speed up Java VM (JVM) startup time?
body: <p>I am running tests that start multiple JVM processes. Summary startup time of JVMs is quite significant compared to time of actual tests that run inside JVM. How do I speed things up?</p>
  
  <p>I have used "-client" option already, this does help but not as much as I wanted. Is there any other way, say preloading bunch of JVMs and reusing them somehow?</p>
