Customer built the application and he complained that 100,000 filled pattern take long time to draw compared to hollow retatangle. In comparison with xlib, java is too slow and is not competitive with other graphic packages.

Customer provided Java application - magma.jar to demostrate this performance issue.

In JDK 1.3.1 under solaris 8.

Rectangle count 100,000 would take a lot less time in millisecond compared to predefined pattern. Customer requests to speed up to draw the filled pattern retangle.

The test was also performed under JDK 1.2.2_08 and SDK beta 1.4. They all show the same problem. The sample applciation running in NT plaform is much faster. However it is still slow in drawing predefined pattern retangle.
