.live() performance issue

.live() performance issue

any ideas why Im experiencing performance decrease would be helpful.

Essentially, I use ajax to bring in dynamic content which contains Cluetip objects. Naturally, the event handler breaks which causes the Cluetip to popup. The fix below seems to allow these cluetip popups to work again. However, the performance is significantly worse than the non dynamically loaded 'test' page. The cluetips can take several seconds to load and sometimes fails with a partial load.

is the .live() behavior constantly trying to reevaluate the content of these cluetip popups? Could my below code be better served in another function outside the <script> tags in the header? Any insight is appreciated.

    $("a.simple").live("mouseover", function(){

        $('a.simple').cluetip({
             cluetipClass: 'simple'
        });
    });
    $("a.basic").live("mouseover", function(){
        $('a.basic').cluetip({
             cluetipClass: 'bbg'
        });
    });
