换了台机器---原来那台没有PHP，新的没有Enterprise Server:
./ab -n 5000 -c 500 http://localhost/readme.html
Requests per second:    268.00
./ab -n 5000 -c 500 http://localhost/readme.php
Requests per second:    200.22
./ab -n 5000 -c 500 http://localhost/readme.jsp
Requests per second:    22.93

这回的JSP引擎是tomcat。它解释的JAVA程序是

import javax.servlet.http.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
