web壓測是否是系統(tǒng)的問題

kiss8212180

網(wǎng)站做測評  有項要求是單臺服務器同時支持在線10到100家企業(yè)（1000人）；
   現(xiàn)在我說下我的環(huán)境：
   Xeon E5504  *2
    8G 內(nèi)存
   sas 300G *2 做raid1
    centos5.4
    nginx+php+mysql
我自己用ab在局域網(wǎng)內(nèi)測如下：

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

用webbench 在服務器上測試如下：

# 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.

在以上的整個測試過程中我訪問web的時候還很順暢 ...整個站加上圖片也很小總共也就152M

然后我得出的結論是整個環(huán)境完全能支持1000人同時在線，然而第三方給做了測試說只能并發(fā)200用戶左右 200以上就上不去了....
這讓我很費解？

第三方在測的時候流量都達到了近400M 如此高的流量才200的并發(fā)么？

chenyx

他們是用什么軟件測試的?流量超高啊

后來問了他們說是用 Mercury LoadRunner 8.1測的
