    Well, I use a faster CPU (C2D E7500 @ 2.93GHz) but that doesn't explain the 2x difference in timing for opening the window. Maybe there are other factors at play (GPU acceleration?)

    It would probably help (on old IE's esp) to alert out the relevant times... or for dynaTrace testing to make sure the methods we should profile are named methods.

    I will play with my downloaded copy to see what I can see about performance.

    Thanks again!

    I see numbers like 180ms for Chrome but 880ms for IE8. I will dig further and see if I can identify the root of the problem. If you don't need splitters or collapsibility you could use table layout to avoid all the nested box layouts. It should help some.

    Thanks for the feedback so far guys, keep it coming. 4.1 is not the final word in performance, we will continue to treat it as a top priority in 4.2 and beyond.

    It got slower again in 4.1 beta 1. Now about 1000 ms for the above example. Anyway, I made an updated test case:
