Does RegisterStartupScript increase the page size

I am using this code in the page:

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:Timer ID="timer" Interval="4000" runat="server" OnTick="timer_Tick" />

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
    <ContentTemplate>
        <asp:Panel ID="pnlAlarm" runat="server" CssClass="pnlAlarm" ClientIDMode="Static">
            <div id="Alarm">
                <asp:Label ID="lblContent" runat="server" Text="Updating" CssClass="AlarmLogo"></asp:Label>
                    ClientIDMode="Static" />
            </div>
        </asp:Panel>
    </ContentTemplate>
    <Triggers>
        <asp:AsyncPostBackTrigger ControlID="timer" />
    </Triggers>
</asp:UpdatePanel>

      

        
        
        
      

    

and in the code behind I am using this simple code:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        Session["nima"] = 1;
    }
}
protected void timer_Tick(object sender, EventArgs e)
{
    int i = int.Parse(Session["nima"].ToString());
    if (i==3)
    {
        lblContent.Text = i.ToString();
        ScriptManager.RegisterStartupScript(this, GetType(), "AlarmMessage", "$('#pnlAlarm').slideToggle();", true);
        Session["nima"] = 0;
    }
    else
    {
        i = i + 1;
        Session["nima"] = i;
    }
}

      

        
        
        
      

    

I want to know every time I use RegisterStartupScript

, $('#pnlAlarm').slideToggle();

add to my page and increase the size of my page?

thanlks
