apache2.4.1放出后据说性能目标直指nginx，所以自己编译安装了两个版本进行静态页的压力测试。
测试服务器为虚拟机 2颗CPU 2G内存。
编译选项：
apache：
./configure –prefix=/usr/local/apache –enable-proxy-http –enable-proxy-fcgi –enable-proxy  –enable-proxy-connect –enable-proxy-ftp –with-apr=/usr/local/apr –with-apr-util=/usr/local/apr-util/
nginx：
./configure –prefix=/usr/local/nginx
相邻机ab压同一静态页
[root@localhost ~]# curl http://192.168.2.129/index.html
test for apache 2.4
数据：
apache：
[root@localhost ~]# ab -n 1000000 -c 100 http://192.168.2.129/index.html

apache的Requests per second达到了7546.16 [#/sec] 而nginx则更胜一筹有9080.85 [#/sec]
其中在apache跑的过程中服务器的负载load 1分钟一度达到了load average: 83.66左右，而nginx则持续在1.5左右，httpd仍然不能算是能和nginx媲美
