MVC4捆绑使用Scripts.Render放缓时， [英] MVC4 Bundling slow when using Scripts.Render

问题描述

提供一个简单的页面呈现捆绑的脚本时，我的asp.net MVC4 Web项目，运行速度非常慢。然而，当我使用'硬codeD脚本标签与虚拟束路径的源属性页面上则表现要好得多：

My asp.net MVC4 web project is running very slowly when serving a simple page that renders bundled scripts. However, when I use a 'hardcoded' script tag on the page with the source attribute of the virtual bundle path then performance is much better:

@Scripts.Render("~/bundles/scripts")                            ~ 4 seconds

VS

<script src='@Scripts.Url("~/bundles/scripts")'></script>       < 1 second

我的 BundleConfig.cs 并没有特殊的配置，这正是因为它似乎：

My BundleConfig.cs has no special configuration, this is exactly as it appears:

bundles.Add(new ScriptBundle("~/bundles/scripts").Include(
    "~/Scripts/jquery-1.7.2.min.js",
    "~/Scripts/jquery.validate.min.js",
    "~/Scripts/jquery.validate.unobtrusive.js",
    "~/Scripts/jquery-ui-1.9.0.custom.min.js",
    "~/Scripts/bootstrap.min.js",
    "~/Scripts/bootstrap-modal.js",
    "~/Scripts/bootstrap-dropdown.js",
    "~/Scripts/bootstrap-tooltip.js",
    "~/Scripts/bootstrap-typeahead.js",
    "~/Scripts/bootstrap-transition.js",
    "~/Scripts/bootstrap-popover.js"));

我的的web.config 即使被配置在调试优化，但我曾尝试在Release模式下运行，仍然得到同样的结果：

My web.config is even configured to optimize in Debug but I have tried running in Release mode and still get the same result:

<compilation optimizeCompilations="true" debug="false" targetFramework="4.0" />

任何想法，为什么 Scripts.Render 很慢？

Any ideas why Scripts.Render is so slow?

推荐答案

的问题是与我已经安装了过时的包。一个简单的更新封装在包管理器控制台，我从去

The problem was with the outdated package I had installed. A simple Update-Package in package manager console and I went from

<package id="Microsoft.AspNet.Web.Optimization"
    version="1.0.0-beta2" targetFramework="net40" />

到

<package id="Microsoft.AspNet.Web.Optimization"
    version="1.0.0" targetFramework="net40" />

现在 Scripts.Render（）是peforming好得多： - ）

Now Scripts.Render() is peforming much better :-)
