Performance-impact Of Empty Page_Load() Methods?

When adding a new page or user control to an ASP.NET webforms application, the code-behind class contains an empty Page_Load() event handler:

public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}

I have an existing web app, where many pages and controls still contain these empty event handlers (they are not used).

Question: Is there any performance impact due to these empty event handlers and should they therefore be removed from all pages and controls?
