Browser is not smooth while using jQuery "replaceWith"

Question

Hi everyone, I'm using jQuery replaceWith to update information of my website. Div elements which are returned are small. The function is called after 5 minutes. When I focus on browser, replaceWith function will run but my browser is not smooth and sometime can crash. Which plugin or solution can I use to resolve the problem ? I used: $('#hotpost').hide().html(newHtml).fadeIn("slow"); and $('#hotpost div.content').hide().replaceWith(newHtml).fadeIn("slow"); Thank you :)
