Ok, first of all thank you everyone in the jQuery team, it's a
fantastic tool!!!
I did all the recommended changes in my methods and these are the
results:
Sample:
$this.getProcessMenuItem = function(li) {
var type = "processMenuItem";
var first = li.find('a:first');
var
It's the calls to $(li).find('li.News a') that make for most of the
difference. Without that 1.3.1 is up to 20% faster.
Apparently a simple descendant selector in 1.3 is terribly slower i.e.
$(el).find('div a') if any s exist (even outside the context). Also
'.someclass a' is faster than 'li.some
A lot has changed with regard to the selector engine in 1.3.1 - it
this case it looks like these type of selections didn't benefit. One
thing that would change that, though, would be caching the selectors
that you do run. Right now you run a couple of these over-and-over
again. I'd probably rewrit
The markup look like this:

No idea about the performance drop, but you can improve your main
function. $(this)[0] is unnecessary, you're creating a new jQuery
object and throwing it away.
// MAIN
function getMenuItems(menu) {
var menuItems =
No idea about the performance drop, but you can improve your main
function:
// MAIN
function getMenuItems(menu) {
var menuItems = [];
$(menu).find('.MenuItem').each(function(){
var t = $(this), item = false;
if (t.hasClass('processMenuItem')) item = getProcessMenuItem
(this);
Do you have some sample markup? It's kind of hard to determine from
just the code.
