【在 midi (迷笛) 的大作中提到: 】
∶ 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

这个我在测试也发现了,tomcat绝对有问题,不管怎样,它的响应速度
总是在20-30之间,甚至和机器无关 :) 远不如GNUJSP的效率高
