I'm running it as a script with: java -server -cp clojure.jar clojure.lang.Script mandelbrot.clj
as I mentioned earlier, I did try forcing all the primitives, but didn't notice much of a difference, I did try running the draw method repeatedly to make sure it wasn't just the startup times causing it to run slow. as a note I also tried a jython version and it runs about twice as fast for me, which I think is comparable, and it could just mean that there is a hit on performance over java that only so much can be done about. I'm mostly curious if I made any newbie mistakes that would cause it to perform a lot worse than it should. I do expect pure java to run faster in the end.
