Hi
Please look at the following code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="lixo.aspx.cs" Inherits="lixo" %>
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="ajaxToolkit" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
<link rel="stylesheet" type="text/css" href="http://programamos.pt/cheirabem/css/geral.css"/>
<link rel="stylesheet" type="text/css" href="css/geral.css">
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<ajaxToolkit:TabContainer ID="TabContainer1" Visible="true" runat="server">
<ajaxToolkit:TabPanel runat="server" HeaderText="ola">
<ContentTemplate>tests</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
</div>
</form>
</body>
</html>
It works fine on localhost

But not on my website as you can test at:
http://programamos.pt/cheirabem/lixo.aspx
And my website runs very slow when I use ajaxtoolkit.
All the files are on Bin folder (inside httpdocs) as image below

Any help?
