[jQuery] Lower speed with 1.3.1 vs 1.2.6 with simple parsing

[jQuery] Lower speed with 1.3.1 vs 1.2.6 with simple parsing


Hi!,
When switching between 1.3.1 and 1.2.6 i get a serious drop in speed
when collection a JSON object from static HTML content.
1.2.6
FF: 325ms
Safari: 75ms
IE7: 450ms
1.3.1
FF: 1205ms
Safari: 415ms
IE7: 1550 ms
The javascript collects data into a JSON object with a few methods
like this:
// MAIN
function getMenuItems(menu) {
    var menuItems = [];
    $(menu).find('.MenuItem').each(function(){
        var item = false;
        if ($(this).hasClass('processMenuItem')) item = getProcessMenuItem($
(this)[0]);
        if ($(this).hasClass('softwareMenuItem')) item = getSoftwareMenuItem
($(this)[0]);
        if ($(this).hasClass('listMenuItem')) item = getListMenuItem($(this)
[0]);
        if ($(this).hasClass('aboutMenuItem')) item = getAboutMenuItem($
(this)[0]);
        menuItems.push(item);
    });
    return menuItems;
};
// COLLECTOR
function getProcessMenuItem(li) {
    var type = "processMenuItem";
    var item = {
        "id" : $(li).attr('id'),
        "type" : type,
        "title" : $(li).find('a:first').text(),
        "URI": $(li).find('a:first').attr('href'),
        "preamble" : $(li).find('li.Intro h4').text(),
        "body" : $(li).find('li.Intro p').text(),
        "news" : {
            "title" : $(li).find('li.News a').text(),
            "URI" : $(li).find('li.News a').attr('href'),
            "summary" : $(li).find('li.News a').attr('title')
        },
        "splash" : {
            "title" : $(li).find('li.Splash a').text(),
            "URI" : $(li).find('li.Splash a').attr('href'),
            "summary" : $(li).find('li.Splash a').attr('title'),
            "media" : $(li).find('li.Splash img').attr('src')
        },
        "links" : getAnchorLinks(li)
    };
    return item;
};
Anyone else experiencing drops in speed with 1.3.1 doing simple stuff
like this?
Sure, I was not expecting any major speed increase since the code is
not optimized yet, but an 80% drop is just crazy...
Please advice,
