我的问题

对于我的Web应用程序，页面的初始加载时间超过20秒。在Chrome上-Audit -LightHouse显示以下信息。

我不知道如何解决这个问题，以使我的页面加载速度更快。我已经很长时间了。

在下面，我详细介绍了如何在部分布局和主页中捆绑和呈现捆绑包。任何帮助都非常感谢。

下面是我的js和css文件捆绑包。

     SELECT SELECT  NVL(TO_CHAR(TRANS.ID), 'NULL') AS ID
       , 'HEADER'

       ,NVL(TO_CHAR((SELECT L_APP.DESCRIPTION  
  FROM  L_APP L_APP



      WHERE  EXISTS  ( SELECT 1 FROM TRANS WHERE L_APP.APP =                  TRANS.APP AND LANGUAGE = 2


      )

         )), 'NULL') AS KEY_EVENT

在我的_Layout.cshtml

在局部视图（_Lyout.cshtml）的开始处，我呈现了以下内容

  bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                    "~/Scripts/jquery-{version}.js"));/*2.1.1*/

        bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                    "~/Scripts/jquery.validate*"));

        bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include(
                    "~/Scripts/jquery-ui.js"));

        // Use the development version of Modernizr to develop with and learn from. Then, when you're
        // ready for production, use the build tool at https://modernizr.com to pick only the tests you need.
        bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                    "~/Scripts/modernizr-*"));

        bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(

                  "~/Content/jQuery_Slider_Pips/js/jquery-ui-slider-pips.js"));//,
                                                                               //"~/Scripts/respond.js"));

        bundles.Add(new ScriptBundle("~/bundles/highcharts").Include(
                  "~/Scripts/HighCharts/highcharts.js",
                  "~/Scripts/HighCharts/highcharts-more.js",

                  );

                 );



        bundles.Add(new ScriptBundle("~/bundles/signalgen").Include(
                    "~/Scripts/SignalScripts/SignalGenScript.js"));

        bundles.Add(new ScriptBundle("~/bundles/signaldata").Include(
                    "~/Scripts/SignalScripts/SignalDataScript.js"));

        bundles.Add(new ScriptBundle("~/bundles/signaldatacompare").Include(
                    "~/Scripts/SignalScripts/SignalScript.js"));

        bundles.Add(new ScriptBundle("~/bundles/signaldatareport").Include(
                    "~/Scripts/SignalScripts/SignalReportScript.js"));

        bundles.Add(new ScriptBundle("~/bundles/signaldataalarm").Include(
                    "~/Scripts/SignalScripts/SignalAlarmScript.js"));

        bundles.Add(new ScriptBundle("~/bundles/signalmaster").Include(
                    "~/Scripts/SignalScripts/SignalMasterScript.js",
                    "~/Scripts/Misc/jscolor.js"));

        //bundles.Add(new ScriptBundle("~/bundles/highcharts").IncludeDirectory("~/Scripts/HighCharts","*.js"));


        bundles.Add(new StyleBundle("~/Content/css").Include(
                  "~/Content/bootstrap.css",
                  "~/Content/site.css"//,

                  ));

        bundles.Add(new StyleBundle("~/Content/papercss").Include(
                   "~/Content/assets/css/paper-dashboard.css",
                   // "~/Content/assets/css/themify-icons.css",
                  //"~/Content/Custom/site_layout/css/bootstrap-responsive.min.css"//,

                 "~/Content/TinyDateTimePicker/datePicker.css",
                 "~/Content/TinyDateTimePicker/themes/white/datePicker.css"));

在部分视图（_Layout.cshtml）的结尾处，我呈现了以下脚本

<title>@ViewBag.Title - Dashboard - IO </title>
@Styles.Render("~/Content/css")

@Scripts.Render("~/bundles/modernizr")

在我的index.cshtml中，我在最终视图中具有以下代码

 @Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/jqueryui")
@Scripts.Render("~/bundles/bootstrap")
@Scripts.Render("~/bundles/signalgen")

@RenderSection("Scripts", required: false)
@Scripts.Render("~/bundles/jqueryval")
@Scripts.Render("~/bundles/highcharts")</body>

延迟/异步非关键js。
组合css / js文件以最小化请求。
与外部域进行预连接，例如：

预加载css / js，例如：

<！-预加载资源 –––––––––––––––––––––––––––––––––––––––––––––––– ->

<!-- FONT
–––––––––––––––––––––––––––––––––––––––––––––––––– -->
<link href='//fonts.googleapis.com/css?family=Raleway:400,300,600' rel='stylesheet' type='text/css'>

<!-- CSS
–––––––––––––––––––––––––––––––––––––––––––––––––– -->
<link rel="stylesheet" href="http://www.pagespeedinsights.org/theme/css/normalize.css">
<link rel="stylesheet" href="http://www.pagespeedinsights.org/theme/css/skeleton.css">
<link rel="stylesheet" href="http://www.pagespeedinsights.org/theme/css/custom.css" >
