web压测是否是系统的问题

kiss8212180

网站做测评  有项要求是单台服务器同时支持在线10到100家企业（1000人）；
   现在我说下我的环境：
   Xeon E5504  *2
    8G 内存
   sas 300G *2 做raid1
    centos5.4
    nginx+php+mysql
我自己用ab在局域网内测如下：

./ab -c 500 -n 100000 http://www.xxxxxxxx.com/test.php

用webbench 在服务器上测试如下：

# webbench -c 5000 -t 30 http://www.xxxxx.com/test.php
Webbench - Simple Web Benchmark 1.5
Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software.

Benchmarking: GET http://www.xxxx.com/test.php
5000 clients, running 30 sec.

Speed=177872 pages/min, 5807245 bytes/sec.
Requests: 88936 susceed, 0 failed.

在以上的整个测试过程中我访问web的时候还很顺畅 ...整个站加上图片也很小总共也就152M

然后我得出的结论是整个环境完全能支持1000人同时在线，然而第三方给做了测试说只能并发200用户左右 200以上就上不去了....
这让我很费解？

第三方在测的时候流量都达到了近400M 如此高的流量才200的并发么？

他们是用什么软件测试的?流量超高啊

后来问了他们说是用 Mercury LoadRunner 8.1测的
