Jython Speed vs Java

I have created a small benchmark , to test the speed of Jython when calling swing components and JAVA2D methods. I was aiming to 5x times slower speed in JYTHON but JYTHON proved me very wrong. IT was only 3 times slower than JAVA.

The benchmark was not only for speed reasons but also a way to learn Jython .

I share with you the code of both JAVA and Jython. You may run the test in your computer and share results.

The app is building a window and draws 1 point lines and then displays a very large button with the amount of nanoseconds it took to execute the program.

I run the test in a ACER ASPIRE ONE with 1.GHz Pentium Atom Processor, 500 MB RAM, 8 GB SDD HD and WINXP.
