Java Virtual Matchine compiles "on-fly" simple applications, therefore e.g. the Mandelbrot set applet is only 25% slower than the corresponding C program (results may depend on chips and JVMs). The PIMC applet above makes every "Step" 106 MC iterations for T=0.65 sec on Athlon1500+ and IE6 (you can see your time in the Status bar).
