Ajax delay simulation

I have a small ajax jquery script that returns XML to me. While it works and communicates with the server, I show the animation of the bootloader.

The problem is that I do not see the animation. Either I did something wrong, or the network connection is really fast.

Does anyone know how I can imagine a delay for my ajax code to slow down the process and I can check the animation function?

Thank.

ps: given ajax code, just incase

function fetchData($nodeid, $area){
    if( $nodeid != $currentRoomId ){
        popupBox($area);//$area, $roomInfo);
    }

        var $nid, $title, $classroom, $boardroom, $cabaret;
        $.ajax({

            url: "/room/" + $nodeid + "/rss.xml",
            dataType: "xml",
            success: function($xml){

                $returnXML  =   $xml;
                $($xml).find('node > *').each(
                    function(){

                        switch( $(this).attr('name') ){
                            case 'Nid':
                                $nid    =   $(this).text();
                            break;
                            case 'Title':
                                $title  =   $(this).text();
