服务器并发能力测试 Apache Beach

D:\wamp\bin\apache\Apache2.2.11\bin>

4.输入测试数据 -n1000 -c10 http://localhost/oop5.php

-n1000表示总请求数为1000

-c10表示并发用户数为10

http://localhost/oop5.php表示请求的超链接地址

Server Software:        Apache/2.2.11 被测试的web服务器名称，它来自HTTP响应数据的头信息

Server Hostname:        localhost 请求URL中主机部分名称，它来自HTTP请求数据的头信息

Server Port:            80被测试web服务器的监听端口

Document Path:          /oop5.php 表示请求URL中的根绝对路径，它来自HTTP请求数据的头信息

Document Length:        222 bytes表示HTTP响应数据的正文长度

Concurrency Level:      10 并发数

Time taken for tests:   5.125 seconds表示所有请求被处理完成所需要的总时间

Complete requests:      1000 完成的实际请求数

Failed requests:        0失败的请求数

Write errors:           0请求写入失败的次数

Total transferred:      409000 bytes表示所有请求的响应数据长度总和（header length + context length）
