I can confirm that the JavaScript engine in IE is horribly slow compared to any other browser. Reusing objects helps dramatically because IE is also horrible at freeing memory. Even if you clear all your objects out, IE may never release them. It is so bad, that not even closing the page and reopening it helps. I have found the memory usage to be so bad that the only way to reclaim it is to close the browser and start over. And this has nothing to to with qooxdoo, it is entirely an IE bug that can not be overcome with code. I have not done drastic testing with IE8, I hope it is better then 6 & 7.
