Why do the demos run slowly?
Make sure that you are running the most recent released version of Netscape Navigator or Microsoft Internet Explorer. These browsers are able to compile Java code on the fly, which makes the applications run much, much faster than previous versions. Still, running these demos using a browser across the Internet is the slowest way to use them. Running these demos locally or using Java utilities such as ‘appletviewer’ result in much better performance. Once you’ve done something for the first time (like scroll a window) all subsequent scrolling will be faster.
