Given the nature of the script, is this a Javascript problem or a page rendering problem? Even Internet Explorer turns out a better time on this test.

Reproducible: Always

Actual Results:  
Depending on which program, other browsers are 2-20 TIMES faster. Could not find any other program slower, except FireFox 2. :)

Expected Results:  
In line with other scripting tests, and with continued improvements in the speed of the Firefox core, I really did not think the program would....die....

More that I can not understand why this result is not five times faster.

Given the translation to HTML and the continuous redrawing, is this entirely Gecko's fault? Or is this a limited case that has not received any optimizations?

It's not even Java, it's JavaScript.

Sorry, mistyped the title. I did specify JavaScript in the body. Continuing in the other bug.
