其实之前http 2.4.1刚出来的时候就很多做对比的了。 大部分分测试表明对于静态文件而已，nginx的性能还是会稍微好些，但是event模式下的httpd比之前的性能是提升得太多太多了。httpd安装起来比较麻烦，尤其是在老掉牙的机器上。
httpd 2.4.4在RHEL 4.8的安装过程大概这样的：
- 下载最新的httpd 2.4.4解压，然后再下载apr-1.4.6.tar.bz2和apr-util-1.5.1.tar.bz2放到httpd目录下的srclib,解压后把文件夹更名为apr和apr-util.2.安装新版的pcre，我直接在sourceforge.net上下载的.然后编译安装pcre./configure –prefix=/opt/install/pcre-8.32 –enable-pcre32 –enable-jit –enable-utf –enable-pcre16
[sourceforge.net]( http://downloads.sourceforge.net/project/pcre/pcre/8.32/pcre-8.32.tar.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fpcre%2Ffiles%2Fpcre%2F8.32%2F&ts=1362923206&use_mirror=nchc)
3.配置httpd编译./configure –prefix=/opt/install/httpd-2.4.4 –enable-rewrite –enable-cache –enable-ssl –enable-static-ab –enable-ssl –with-included-apr –with-pcre=/opt/install/pcre-8.32/–with-mpm=event
安装好后简单做了一个测试，0.6k的小页面。

从图可以看出httpd 2.4.4在高并发的还是略逊于nginx。
