Windows Azure的或IIS在inital负荷缓慢 [英] windows azure or IIS slow in inital load

问题描述

我有一个Windows Azure中举办了简单的个人MVC4的Web应用程序。

I have a simple personal MVC4 web app that is hosted in Windows Azure.

此Web应用程序在使用非常小，初始呼叫很慢特别是当我试图在早上点击。

This web app is very minimal in use, the initial call is very slow specially when I tried to click in the morning.

我怀疑该IIS是睡觉，而且需要唤醒。我发现这篇文章，并提到这是在IIS中的http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/8b3258e7-261c-49a0-888c-0b3e68b2af13这需要在IIS中设置了，但我的web应用程序中的Azure托管，有没有办法做一些在Web.config文件中设置的？

I’m suspecting that the IIS is sleeping and need to wake up. I found this article and mention that this is a bug in IIS http://social.msdn.microsoft.com/Forums/en-US/wcf/thread/8b3258e7-261c-49a0-888c-0b3e68b2af13 which required setting up in IIS but my web app is hosted in Azure, is there any way to do some sort of setting in Web.config file?

所有后续调用是快速。

All succeeding calls are fast.

推荐答案

有两种选择：

1. 启动任务


2. 的OnStart code

有关启动任务，请参见此链接

For startup tasks, see this link.

有关的OnStart code，尝试这样的功能（这个功能做了一些事情，太）：

For OnStart code, try a function like this (this function does a few more things, too):

    private const string _web_app_project_name = "Web";

    public static void SetupDefaultEgConfiguration(int idleTimeoutInMinutes = 1440, int recycleTimeoutInMinutes = 1440, string appPoolName = "My Azure App Pool", bool enableCompression = true)
    {
        if (!RoleEnvironment.IsEmulated)
        {
            Trace.TraceWarning("Changing IIS settings upon role's OnStart. Inputs: ({0}, {1}, {2}, {3}", idleTimeoutInMinutes, recycleTimeoutInMinutes, appPoolName, enableCompression);

            // Tweak IIS Settings
            using (var iisManager = new ServerManager())
            {
                try
                {
                    var roleSite = iisManager.Sites[RoleEnvironment.CurrentRoleInstance.Id + "_" + _web_app_project_name];
                    if (enableCompression)
                    {
                        //================ Enable or disable static/Dynamic compression ===================//
                        var config = roleSite.GetWebConfiguration();
                        var urlCompressionSection = config.GetSection("system.webServer/urlCompression");
                        urlCompressionSection["doStaticCompression"] = true;
                        urlCompressionSection["doDynamicCompression"] = true;
                        Trace.TraceWarning("Changing IIS settings to enable static and dynamic compression");
                    }

                    //================ To change ApplicationPool name ================================//
                    var app = roleSite.Applications.First();
                    app.ApplicationPoolName = appPoolName;

                    //================ To change ApplicationPool Recycle Timeout ================================//
                    var appPool = iisManager.ApplicationPools[app.ApplicationPoolName];
                    appPool.Recycling.PeriodicRestart.Time = new TimeSpan(0, recycleTimeoutInMinutes, 0);

                    //================ idletimeout ====================================================//               
                    var defaultIdleTimeout = iisManager.ApplicationPoolDefaults.ProcessModel.IdleTimeout;
                    var newIdleTimeout = new TimeSpan(0, idleTimeoutInMinutes, 0);
                    if ((int)newIdleTimeout.TotalMinutes != (int)defaultIdleTimeout.TotalMinutes)
                    {
                        appPool.ProcessModel.IdleTimeout = newIdleTimeout;
                    }

                    // Commit the changes done to server manager.
                    iisManager.CommitChanges();
                }
                catch (Exception e)
                {
                    Trace.TraceError("Failure when configuring IIS in Azure: " + e.ToString().Take(63000));
                }
            }
        }
    }
