The problem is my sketches are very slowly. But not the other's. 

For examples, this example,  http://www.openprocessing.org/visuals/?visualID=6268 runs very fast, if I download the applet, and I run it locally, it's very fast too. 

But when I download the source code, and I run this code, It is very slow. I've tried to export an applet and application, but they run very slow too...
