example file that seems to get slower when used with hotspot JVM. Us

        long count = 0;
        for (int x = 0; x < 10000000; x++) {
          in.go(in);
        }
        System.out.println("for loop took:     " + (System.nanoTime() - start)/1000000);
        in3 = in; 
        in4 = in;
        start = System.nanoTime();
        count = 0;
        for (int x = 0; x < 10000000; x++) {
          //go2(in, in); // either of these two lines don't seem be faster, under server JVM
          go3();
        }
        System.out.println("method call took:  " + (System.nanoTime() - start)/1000000);
      }
    }
  }

I guess my real hope would have been "is there some setting I can tweak so that the second loop takes as long as the first loop [0ms] since that it really fast and I would love to have the speedup" (apparently hotspot is smart, but that not smart, unfortunately). ??
