MVC 架构的网站，如何计算页面加载时间？

[DigJim]

如果是ASP.net的页面，可以在页面附属的CS文件中这样做，但是MVC架构的网页，如何处理呢？

         DateTime dt;  
        protected override void OnPreInit(EventArgs e)  
        {  
            dt = DateTime.Now;  
            base.OnPreInit(e);  
        }  
        public override void RenderControl(HtmlTextWriter writer)  
        {  
            base.RenderControl(writer);  
            TimeSpan ts = DateTime.Now - dt;  
            Response.Write("加载页面用时：" + ts.TotalMilliseconds);  
        }

controller action

写一个自定义的ActionFilter
如：

    public class MyActionFilter :FilterAttribute,IActionFilter
    {

        #region IActionFilter 成员

        void IActionFilter.OnActionExecuted(ActionExecutedContext filterContext)
        {
            filterContext.Controller.ViewData["ActionExcuted"]="Action执行完毕，时间："+DateTime.Now.ToString();
        }

        void IActionFilter.OnActionExecuting(ActionExecutingContext filterContext)
        {
            filterContext.Controller.ViewData["ActionStarted"]="Action开始执行，时间："+DateTime.Now.ToString();
        }

        #endregion
    }
