7.1. 压测环境

7.1.1. 压测平台

压测发起端为台机PC(192.168.6.17)，配置如下：

CPU : Intel Core i3-3240 3.40GHz 3.40GHz内存 : 512MBWindowsXP里面装了VMWARE 10里面装了RedHat Enterprise Linux Server release 5.4 ( 32BITS )

压测网络为百兆有线

压测服务端为台机PC(192.168.6.111)，配置如下：

CPU : AMD E-350 1.60GHz 1.60GHz内存 : 4GBRedHat Enterprise Linux Server release 5.4 ( 32BITS )

7.1.2. 压测客户端

压测客户端采用Apache自带工具ab。

因ab只支持HTTP/1.0而不支持HTTP/1.1，会引发Nginx的压缩和Keep-Alive不能同时开启的BUG，故修改了ab.c中填充HTTP请求版本的代码，重新编译成ab2供压测使用。hetao和Apache则不受影响。

httpd-2.2.17/support/ab.c

  23.    1631             cookie, auth,
  24.    1632             postlen,
  25.    1633             (content_type[0]) ? content_type : "text/plain", hdrs);
  26.    1634     }

7.1.3. 压测服务端

选用以下Web服务器软件做横向压测，版本和配置侦听端口如下：

hetao/0.2.0 && hetao/0.7.0，侦听端口为9527Nginx/1.9.13，侦听端口为9528Apache/2.2.14，侦听端口为9529Tengine/2.1.2，侦听端口为9530

（原计划还有kangle/3.4.8，但是从官网上下载的源代码编译安装始终报错，猜可能是我的Linux编译器gcc版本过低，不支持_sync原子操作，但rhel5.4也不低啊，算了，不用它了）
