2、测试 : php测试
A) 测试方法：我们的测试采用webbench1.5这个软件来模拟clients，分别以200、500、1000、2000个clients去运行30秒；另外采用sar工具来采集数据；
B）采集数据：包括sar工具的cpu、memory、swap输出，sar以每隔5秒的频率共采集3组；
C）采集的页面均是info.php，内容是
| root@ftp: report# cat info.php
|

四、最终总结:
总结见下表:
| clients | sar -ur 5 3 | webbench -c<clients> -t30 url |
| CPU(%) | Memory(M) | pages/s | susceed | failed |
| apache | nginx | apache | nginx | apache | nginx | apache | nginx | apache | nginx |
| 200
Clients | 90 | 87 | 535 | 576 | 824 | 933 | 24725 | 28007 | 0 | 0 |
| 500
Clients | 83 | 86 | 582 | 624 | 832 | 937 | 24876 | 28039 | 98 | 80 |
| 1000
Clients | 88 | 86 | 664 | 697 | 808 | 943 | 24011 | 27917 | 237 | 387 |
| 2000
Clients | 88 | 86 | 775 | 797 | 798 | 935 | 23649 | 27698 | 303 | 516 |
1、 nginx的pages/s比apache在500client以下的情况下快大约100, 但是1000以上后, 差距则越来越小;
2、 而failed率在clients数500以下没有太大差别, 当client越来越多的时候, 则nginx的failed率要比apache多出50%强.
3、 nginx比apache在memory使用上似乎要多一些, 但是因为有FastCGI即ph-cgi的进程存在, 所以就不显得多了.
4、 在请求数量中, nginx的成功数(susceed)要明显多于apache(每次多约4000).
