Hi,

That is ajax action of module SNS ProductTabs. This module using ajax to load data, and it has many data about product.
But we only call ajax SNS ProductTabs when window is loaded(it mean your website is load successful).
==> It dont effect to speed load site. Maybe your tool check dont skip this action. But your can see and check, it only call ajax when window is loaded.

+, To check code: go to file: app/design/frontend/sns_amoda/default/template/sns/producttabs/scripts.phtml find and see the bellow code:

$(window).load(function(){
    itemNav.each(function(){
        if($(this).hasClass('first_load')) $(this).trigger('click');
    });
});

+, To check on your browser: Enable console tab and f5 your browse to see

Thanks!
