关于考试系统的ajax提交单个答案的压力测试

来源：互联网发布：获取python关键字编辑：程序博客网时间：2024/05/20 11:21

其实我一直想知道，究竟一题一题ajax提交答案，也就是说，点击一题的答案，就ajax请求一下服务器，提交一次答案，能否撑到100个用户同时考试呢？

准备环境

asp.net 2.0 + sql2000

ado.net插入数据

web stress application tool(微软出产的web开发压力测试软件)

1.建数据库exam_stress

脚本如下：

CREATE DATABASE exam_stress
GO

USE exam_stress
GO

CREATE TABLE [dbo].[Answer](
[ID] [int] NOT NULL identity primary key, --ID
[QID] [int] NOT NULL, --题目ID
[Answer] [nvarchar](10) COLLATE Chinese_PRC_CI_AS NOT NULL, --答案
[PAID] [int] NOT NULL, --答卷ID
[PID] [int] NOT NULL --试卷ID
) ON [PRIMARY]
GO

表的设计，是二范式与三范式之间

2.建web应用程序

1.建一Default.aspx页面，上面有几个按钮，点击时，发出ajax请求AnswerHandler.ashx

页面代码如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="SubmitAnswerStressTest.Default" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title> <script src="js/jquery-1.3.2.min.js" type="text/javascript"></script> <script type="text/javascript"> window.clickCount = 0; //计算点击的提交用户答案的次数 function go() { $.ajax({ url: 'AnswerHandler.ashx', type: 'post', data: {}, success: function (msg) { window.clickCount++; $("#msg").html(window.clickCount); }, error: function (err) { document.write(err.responseText); } }); } </script></head><body> <% //为了方面显示，所以用小脚本，模拟登录 Session["CurrentUser"] = DateTime.Now.Ticks; %> <form id="form1" runat="server"> <div> <input type="button" value="提交答案" onclick="go();" /><br /> <input type="button" value="提交答案" onclick="go();" /><br /> <input type="button" value="提交答案" onclick="go();" /><br /> <input type="button" value="提交答案" onclick="go();" /><br /> <input type="button" value="提交答案" onclick="go();" /><br /> <input type="button" value="提交答案" onclick="go();" /><br /> </div> <div id="msg"> </div> </form></body></html>

界面如下：

2.建AnswerHandler.ashx文件，直接插入一条数据到Answer表中，代码如下：

using System;using System.Collections.Generic;using System.Web;using System.Data.SqlClient;namespace SubmitAnswerStressTest{ public class AnswerHandler : IHttpHandler, System.Web.SessionState.IReadOnlySessionState /*如果在一般处理程序中，要访问session中的东西的话，就要实现此接口，此接口代表只读*/ { static Random rnd = new Random(); public void ProcessRequest(HttpContext context) { //判断是否有登录 object uidObj = context.Session["CurrentUser"]; if (uidObj == null) { context.Response.Write("error:no login"); context.Response.End(); //调用end方法后，以后执行的Response.Write都会作废 return; } context.Response.ContentType = "text/plain"; SqlConnection conn = new SqlConnection(@"Data Source=192.168.1.3/sql2000;Initial Catalog=exam_stress;User ID=sa;Password=;Min Pool Size=150;Max Pool Size=1000;"); string sql = string.Format("INSERT INTO [Answer] VALUES ('{0}','{0}','{0}','{0}')", rnd.Next()); SqlCommand cmd = new SqlCommand(sql, conn); cmd.Connection.Open(); cmd.ExecuteNonQuery(); cmd.Connection.Close(); context.Response.Write("done!"); } public bool IsReusable { get { return false; } } }}

然后发布到IIS中，进行下一步的压力测试

在http://download.microsoft.com/download/a/8/2/a82e7ba7-c772-4ec4-b186-2cf147f42c11/setup.exe
下载Microsoft Web Application Stress Tool，进行压力测试

相关使用，请参考帮助，或上网查询相关使用资料，其实看得懂英文的话，一般都会使用了。

用户量100，平均1秒点击2次，测试20分钟，操作如下：

先点录制

再输入部署好的站点地址

然后点击100下“提交答案”的按钮

然后停止录制

把用户数设成100个

把delay（延迟）设成0到500

然后开始20分钟的测试

如图所示：

结果如下：

性能一直惟持这种状态

我想，采用这种方式，是可以接受的，既然点击一次提交一次，100个线程，200个用户（我想，可以算是打开100个浏览器来做请求吧）内可以接受，那么这样决定就行了，也不用搞什么一段时间批量保存一下答案这样麻烦，因为，测试是成本，维护也是成本。越复杂的功能，bug就越多。就要越要经过精力与时间的考验

我们做开发的，只想把成本降到最低，无论是开发，维护或者是测试

也许可以换成linq，再做一个测试，对比一下性能。我也想知道，linq在压力下，会是怎样的表现，以前用的，都是开发出来就算了，都没有了解过linq是不是想像中的慢，不过我今天看了一下linq生成的实体类的代码，发觉用到反射的部分很少

这个是Linq写的一般处理程序的代码

using System;using System.Collections.Generic;using System.Web;using System.Data.SqlClient;namespace SubmitAnswerStressTest{ public class AnswerHandler_Linq : IHttpHandler, System.Web.SessionState.IReadOnlySessionState /*如果在一般处理程序中，要访问session中的东西的话，就要实现此接口，此接口代表只读*/ { static Random rnd = new Random(); public void ProcessRequest(HttpContext context) { //判断是否有登录 object uidObj = context.Session["CurrentUser"]; if (uidObj == null) { context.Response.Write("error:no login"); context.Response.End(); //调用end方法后，以后执行的Response.Write都会作废 return; } context.Response.ContentType = "text/plain"; using (DB db = new DB(@"Data Source=192.168.1.3/sql2000;Initial Catalog=exam_stress;User ID=sa;Password=;Min Pool Size=150;Max Pool Size=1000;")) { int randomNum = rnd.Next(); AnswerInfo answerInfo = new AnswerInfo { Answer = randomNum.ToString(), PAID = randomNum, PID = randomNum, QID = randomNum }; db.AnswerInfo.InsertOnSubmit(answerInfo); db.SubmitChanges(); } context.Response.Write("done!"); context.Response.End(); } public bool IsReusable { get { return false; } } }}

性能一直是这样，cpu占用比ado.net高出了一倍

对比之下，其实响应也没有多大差别，不过就是使用linq的话，要求机器的配置要高一些

这只是简单插入的测试比较。

如果是关于复杂的sql语句查询的话（如分数统计等），那就不知道了，有时间，还想亲自测试一下。
