这有什么好苦闷的呢？
好吧，我做了个大符合的测试，在Netscape Enterprise Server 4.0 for Linux上
静态html:
<!doctype html public "-//w3c//dtd html 4.0 transitional//en">
<html>
<head>
   <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
   <meta name="GENERATOR" content="Mozilla/4.5 [en] (WinNT; U) [Netscape]">
</head>
<body>

<center><font size=+2>Netscape Enterprise Server 4.0 Servlets SDK</font></center>

<hr WIDTH="100%">
<br>The following is a set of samples and example components, plugins and
technologies supported by Netscape Enterprise Server 4.0 Servlet Engine. 
This includes binaries, all code, a build enviroment and instructions on
how to install and run.

</body>
</html>

一，将其直接欢名做readme.html
二，将其直接换名做readme.jsp
三，将其直接用在cgi程序中。

测试一，静态连接，共5000个请求，并发500个：

测试二，JSP，5000个请求，并发500个：

Total:        118  1734 10281

测试三，CGI，5000个请求，并发500个
Fail掉了，我没耐心，重启了机器，因为硬盘狂转了一分钟。

将并发用户转为50，
Requests per second分别为：
static HTML: 823.18
JSP: 361.93
对比在重符合情况下静态HTML和JSP的差距348.31/253.32=1.37:1
轻负荷：823.18/361.93=2.27:1
可以看出JAVA Servlet在重符合下的优势。

同一台机器，运行Apache，静态HTML的反应：
500并发用户时327.27
50时：522.52

【在 maht (Trill-TimeKiller) 的大作中提到: 】
∶ 这次，我用过IBM和Sun(Blackdown)的，Inprise不知道怎样，
∶ 也试过Native/Green，奇怪的是Native和Green的区别很小
∶ 在这个样的测试中由于JSP页面很小，所以出现这样的情况
∶ 结果是内存富裕，用不到64M，而CPU是瓶颈
∶ 这样，我相信可能是一个重要的影响，我想搞出个每次都是不一样的
∶ 来比较，不被cache，这样比较才有意义
∶ 你的测试我看过，所以我才认为他的那个是很有问题的。
∶ 但是还是很郁闷
