我在nodejs和IIS之间进行了基本的性能测试。抛出“ hello，world！”时，IIS的速度大约是nodejs的2.5倍。下面的代码。
我的硬件：Dell Latitude E6510，Core i5（双核），8 GB RAM，Windows 7 Enterprise 64位操作系统
节点服务器
runs at http://localhost:9090/
/// <reference path="node-vsdoc.js" />
var http = require("http");
http.createServer(function (request, response) {
response.writeHead(200, { "Content-Type": "text/html" });
response.write("<p>hello, world!</p>");
response.end();
}).listen(9090);
default.htm
hosted by iis at http://localhost/test/
<p>hello, world!</p>
我自己的使用任务并行库的基准测试程序：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net;
using System.Threading;
using System.Threading.Tasks;
using System.Diagnostics;
namespace HttpBench
{
class Program
{
private int TotalCount = 100000;
private int ConcurrentThreads = 1000;
private int failedCount;
private int totalBytes;
private int totalTime;
private int completedCount;
private static object lockObj = new object();
/// <summary>
/// main entry point
/// </summary>
static void Main(string[] args)
{
Program p = new Program();
p.Run(args);
}
/// <summary>
/// actual execution
/// </summary>
private void Run(string[] args)
{
// check command line
if (args.Length == 0)
{
this.PrintUsage();
return;
}
if (args[0] == "/?" || args[0] == "/h")
{
this.PrintUsage();
return;
}
// use parallel library, download data
ParallelOptions options = new ParallelOptions();
options.MaxDegreeOfParallelism = this.ConcurrentThreads;
int start = Environment.TickCount;
Parallel.For(0, this.TotalCount, options, i =>
{
this.DownloadUrl(i, args[0]);
}
);
int end = Environment.TickCount;
// print results
this.Print("Total requests sent: {0}", true, this.TotalCount);
this.Print("Concurrent threads: {0}", true, this.ConcurrentThreads);
this.Print("Total completed requests: {0}", true, this.completedCount);
this.Print("Failed requests: {0}", true, this.failedCount);
this.Print("Sum total of thread times (seconds): {0}", true, this.totalTime / 1000);
this.Print("Total time taken by this program (seconds): {0}", true, (end - start) / 1000);
this.Print("Total bytes: {0}", true, this.totalBytes);
}
/// <summary>
/// download data from the given url
/// </summary>
private void DownloadUrl(int index, string url)
{
using (WebClient client = new WebClient())
{
try
{
int start = Environment.TickCount;
byte[] data = client.DownloadData(url);
int end = Environment.TickCount;
lock (lockObj)
{
this.totalTime = this.totalTime + (end - start);
if (data != null)
{
this.totalBytes = this.totalBytes + data.Length;
}
}
}
catch
{
lock (lockObj) { this.failedCount++; }
}
lock (lockObj)
{
this.completedCount++;
if (this.completedCount % 10000 == 0)
{
this.Print("Completed {0} requests.", true, this.completedCount);
}
}
}
}
/// <summary>
/// print usage of this program
/// </summary>
private void PrintUsage()
{
this.Print("usage: httpbench [options] <url>");
}
/// <summary>
/// print exception message to console
/// </summary>
private void PrintError(string msg, Exception ex = null, params object[] args)
{
StringBuilder sb = new System.Text.StringBuilder();
sb.Append("Error: ");
sb.AppendFormat(msg, args);
if (ex != null)
{
sb.Append("Exception: ");
sb.Append(ex.Message);
}
this.Print(sb.ToString());
}
/// <summary>
/// print to console
/// </summary>
private void Print(string msg, bool isLine = true, params object[] args)
{
if (isLine)
{
Console.WriteLine(msg, args);
}
else
{
Console.Write(msg, args);
}
}
}
}
结果：

结论：IIS比nodejs快约2.5倍（在Windows上）。这是一个非常基本的测试，绝不是结论性的。但是我相信这是一个很好的起点。在其他Web服务器和其他平台上，Nodejs可能更快，但在Windows IIS上胜出。希望将ASP.NET MVC转换为nodejs的开发人员应该暂停并三思而后行。
已更新（5/17/2012）Tomcat（在Windows上）似乎击败了IIS，在抛出静态html方面比IIS快约3倍。

更新后的结论：我多次运行基准程序。Tomcat似乎是在WINDOWS上分发STATIC HTML的最快服务器。
更新日期（5/18/2012）以前，我总共有100,000个请求，同时有10,000个并发请求。我将其增加到1,000,000个总请求和100,000个并发请求。IIS成为尖叫的赢家，Nodejs表现最差。我将以下结果制成表格：
