Response Time of "Hello" Page

This section provides a tutorial example on testing the response time of a simple 'Hello' ASP script page.

The next area I want test is total response time of ASP pages. To do this, I wrote the following Java program. This program is doing a single HTTP request to a specified Web page, and repeating this for many times.

/**
 * HttpResponseTest.java
 * Copyright (c) 2002 by Dr. Herong Yang. All rights reserved.

import java.io.*;
import java.net.*;
public class HttpResponseTest {
   public static void main(String[] args) {
      int numberOfTests = 1;
      if (args.length > 0) numberOfTests 
         = Integer.valueOf(args[0]).intValue();
      long t1 = System.currentTimeMillis();
      String result = "";
      for (int nTest=1; nTest<=numberOfTests; nTest++) {
         result = test(args);
      }
      long t2 = System.currentTimeMillis();
      long t = t2 - t1;
      PrintStream out = System.out;
      out.println("Performance Information:");
      out.println("   Number of tests = " + numberOfTests);
      out.println("   Time = " + (t/1000) + " seconds.");
      out.println("Rerulst of Last Test:");
      out.println(result);
   }
   public static String test(String[] args) {
      String path = "/index.html";
      int port = 80;
      String host = "localhost";
      if (args.length > 1) path = args[1];
      if (args.length > 2) port
         = Integer.valueOf(args[2]).intValue();
      if (args.length > 3) host = args[3];
      String result = "";
      try {
         Socket c = new Socket(host,port);
         BufferedWriter w = new BufferedWriter(new OutputStreamWriter(
            c.getOutputStream()));
         BufferedReader r = new BufferedReader(new InputStreamReader(
            c.getInputStream()));
         String m = "GET "+path;
         w.write(m,0,m.length());
         w.newLine();
         w.flush();
         while ((m=r.readLine())!= null) {
            result = result + m + "\n";
         }
         w.close();
         r.close();
         c.close();
      } catch (IOException e) {
         System.err.println(e.toString());
      }
      return result;      
   }
}

Now compile this program and try it with the following "Hello" ASP page, hello.asp:

<%@ language="vbscript"%>
<html><body>
<%
response.write("Hello world!")
%>
</body></html>

you will get something similar to this:

\local\j2sdk1.4.1_01\bin\java -cp . HttpResponseTest 1 /asp/hello.asp
Performance Information:
   Number of tests = 1
   Time = 0 seconds.
Rerulst of Last Test:
HTTP/1.1 200 OK
Server: Microsoft-IIS/5.0
Date: Tue, 24 Dec 2002 02:47:31 GMT
Connection: Keep-Alive
Content-Length: 38
Content-Type: text/html
Set-Cookie: ASPSESSIONIDGGGQQWLY=BJINNIGBFMBPMNHNNCJFDJLG; path=/
Cache-control: private

<html><body>Hello world!</body></html>

I repeated the tests by changes the controlling parameters. The following table shows the results comparing with similar tests I did with other technologies:

        Number     Debug   Time

1.      1000       No      2       Static text with IIS 5.0

3.      1000       No      6       ASP page with IIS 5.0
