我该如何实现我的网站有更好的表现 [英] How do I achieve a better performance of my website

问题描述

海兰有！

我在Windows 2008服务器上运行的IIS7。结果
在偷看时候，我们有以下行为：

• CPU负载空闲附近


• 请求得到排队（与资源监视器监控）​​


• Exeuction时间获得超过10秒

的 1-4）请参阅previous版本和修改的

5）做的东西异步

的建议，我创建了一个简单的网页...一个页面...这个codebehind：

 使用系统;
使用的System.Threading;
使用的System.Web;
使用System.Web.UI程序;命名空间PerformanceTest
{
    公共部分类AsyncPage：页
    {
        保护覆盖无效的OnInit（EventArgs的发送）
        {
            base.OnInit（E）;            VAR pageAsyncTask =新PageAsyncTask（this.BeginAsyncOperation，this.EndAsyncOperation，this.TimeoutAsyncOperation，NULL）;
            this.RegisterAsyncTask（pageAsyncTask）;
            // 要么
            //this.AddOn$p$pRenderCompleteAsync(this.BeginAsyncOperation，this.EndAsyncOperation）;            //这可能是做清理或某事一样有用
            这preRenderComplete + =手柄preRenderComplete;
        }        私人无效手柄preRenderComplete（对象发件人，EventArgs的发送）
        {
            this.Trace.Write（处理preRenderComplete）;
            this.Trace.Write（的String.Format（managedThreadId＃{0}，Thread.CurrentThread.ManagedThreadId））;
        }        私人委托无效睡眠（INT毫秒）;        私人IAsyncResult的BeginAsyncOperation（对象发件人，EventArgs的，的AsyncCallback的AsyncCallback，对象状态）
        {
            this.Trace.Write（BeginAsyncOperation）;
            this.Trace.Write（的String.Format（managedThreadId＃{0}，Thread.CurrentThread.ManagedThreadId））;            VAR睡眠=新睡眠（Thread.sleep代码）;
            返回sleep.BeginInvoke（1000，的AsyncCallback，状态）;
        }        私人无效EndAsyncOperation（IAsyncResult的asyncResult）
        {
            this.Trace.Write（EndAsyncOperation）;
            this.Trace.Write（的String.Format（managedThreadId＃{0}，Thread.CurrentThread.ManagedThreadId））;
        }        私人无效TimeoutAsyncOperation（IAsyncResult的asyncResult）
        {
            this.Trace.Write（TimeoutAsyncOperation）;
            this.Trace.Write（的String.Format（managedThreadId＃{0}，Thread.CurrentThread.ManagedThreadId））;
        }
    }
}
 

好像也不错，不是吗？其实这改变不了什么，因为强调需要超过30秒，响应时间上升到8秒，CPU占用率接近0％。

6）更新的machine.config

 ＆LT; system.net＆GT;
    ＆LT; connectionManagement＆GT;
        ＆LT;添加地址=*MAXCONNECTION =12/＆GT;
    ＆LT; / connectionManagement＆GT;
＆LT; /system.net>
＆LT;＆的System.Web GT;
    ＆LT;中processModel AUTOCONFIG =真
                  maxWorkerThreads =100
                  maxIoThreads =100
                  minWorkerThreads =50
                  minIoThreads =50/＆GT;
    ＆LT;的httpRuntime minFreeThreads =88
                 minLocalRequestFreeThreads =76/＆GT;＆LT; /system.web>

Hy there!

I'm running IIS7 on a Windows 2008 server.
On peek times we have following behaviour:

• CPU load is near idle
• Requests get queued (monitored with Resource Monitor)
• Exeuction time gets over 10sec

1-4) Please see previous versions and edits

5) Doing stuff async

As suggested, I've created a simple web ... one page ... with this codebehind:

using System;
using System.Threading;
using System.Web;
using System.Web.UI;

namespace PerformanceTest
{
    public partial class AsyncPage : Page
    {
        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);

            var pageAsyncTask = new PageAsyncTask(this.BeginAsyncOperation, this.EndAsyncOperation, this.TimeoutAsyncOperation, null);
            this.RegisterAsyncTask(pageAsyncTask);
            // or
            //this.AddOnPreRenderCompleteAsync(this.BeginAsyncOperation, this.EndAsyncOperation);

            // this might be useful for doing cleanup or sth alike
            this.PreRenderComplete += HandlePreRenderComplete;
        }

        private void HandlePreRenderComplete(object sender, EventArgs e)
        {
            this.Trace.Write("HandlePreRenderComplete");
            this.Trace.Write(string.Format("managedThreadId #{0}", Thread.CurrentThread.ManagedThreadId));
        }

        private delegate void Sleep(int miliseconds);

        private IAsyncResult BeginAsyncOperation(object sender, EventArgs e, AsyncCallback asyncCallback, object state)
        {
            this.Trace.Write("BeginAsyncOperation");
            this.Trace.Write(string.Format("managedThreadId #{0}", Thread.CurrentThread.ManagedThreadId));

            var sleep = new Sleep(Thread.Sleep);
            return sleep.BeginInvoke(1000, asyncCallback, state);
        }

        private void EndAsyncOperation(IAsyncResult asyncResult)
        {
            this.Trace.Write("EndAsyncOperation");
            this.Trace.Write(string.Format("managedThreadId #{0}", Thread.CurrentThread.ManagedThreadId));
        }

        private void TimeoutAsyncOperation(IAsyncResult asyncResult)
        {
            this.Trace.Write("TimeoutAsyncOperation");
            this.Trace.Write(string.Format("managedThreadId #{0}", Thread.CurrentThread.ManagedThreadId));
        }
    }
}

Seems quite good, doesn't it? Actually it changes nothing, as stressing for more than 30 seconds, response time goes up to 8 seconds with CPU usage near 0%.

6) Updated machine.config

<system.net>
    <connectionManagement>
        <add address="*" maxconnection="12" />
    </connectionManagement>
</system.net>
<system.web>
    <processModel autoConfig="true"
                  maxWorkerThreads="100"
                  maxIoThreads="100"
                  minWorkerThreads="50"
                  minIoThreads="50" />
    <httpRuntime minFreeThreads="88"
                 minLocalRequestFreeThreads="76" />

</system.web>
