Agree with Pascal. TJ: Maybe you can tell us what your application consists of so that it gets easier to identify and isolate a DOM manipulation performance problem (if this is the case). Does it have some kind of table with lots of elements? or maybe a listbox with lots of entries?
For those problems, probably creating content using innerHTML instead of appending node elements to the DOM tree will improve your performance a lot and make your application usable even in IE7. You may look at the latest cell based widgets for more info: http://code.google.com/webtoolkit/doc/latest/DevGuideUiCellWidgets.html#selection Hope this helps, Martin On Thu, Feb 10, 2011 at 5:17 PM, Pascal <zig...@gmail.com> wrote: > One place where you might want to start looking is DOM manipulation. > IE is much slower at everything but the DOM can kill your app > performance quicker than anything else. > > An example we ran into, creating a table dynamically.
