Massimo, One of the most appealing things about Qooxdoo is that it abstracts away the browser differences. It seems to me that we are going back to where we started from if we start writing browser specific code. My personal philosophy is to write my code the best that I can and let the pieces fall where they may. You may not have this luxury, but I cannot make myself start trying to optimize code for various browsers. At this point my only recourse is to point people toward the better browsers. It was nice to see some actual numbers showing the difference in speed. I know that this is not what you asked, but it is my 2 cents worth on the topic. btw IE8 does seem to be noticeably faster than IE7.
