title: Fastest scripting language for Java?
body: <p>I'm making a <a href="http://en.wikipedia.org/wiki/Falling_sand_game" rel="nofollow">falling sand game</a> in Java. I want users to be able to write their own engine for the game and I thought a scripting language might work for that. I've tried out a small script with jython and it's many times slower than that java version.</p>
  
  <p>I need a scripting language that has fast loops and/or fast array access since that's what the game will be doing a lot of. Or if you have any suggestions on another way to let users write their own engine for the game. </p>
  
  <p>I'm also not entirely sure this can work (well). If you don't think it can please let me know why and maybe some possible alternatives.</p>
