nginx +php-cgi，apahce+php-cli，cgi的比较

一，突发神精，来把它们三儿来比较

在网上看到好多文章说nginx有多么，多么好。不管好不好，看看测试结果在说，

1，nginx＋php-cgi说明

nginx我开启了11个进程，php-cgi我开启了10个进程

2，apache＋php-cgi说明

httpd我开启了11个进程，php-cgi我开启了10个进程

3，apache＋php-cli说明

没作任何限制

二，测试文件一test.php无逻辑文件

1，nginx+php-cgi

四，个人分析
1，针对无逻辑文件，或者静态文件
在内存，cpu都没有最大化利用的情况下nginx＋php-cgi效果比apache+php-cli的效果好一点，而apache+php-cli是最大化用内存和cpu，由起可见，nginx＋php-cgi的对无罗辑或静态文件的解析要好很多。apache+php-cgi的效果很差，虽然php官方力挺php-cgi，但是根apache的配合效果不好。
2，针对逻辑复杂的文件
针对逻辑复杂的文件时，nginx＋php-cgi对php的解析的效果下降了，但是下降的不是很厉害。而apache＋php-cli对php的解析的效果去增强了，增加了很多，是原来的差不多1.5倍。nginx＋php-cgi在利用部分内存和CPU的情况下根apache＋php-cli对php的解析都差不了多少，个人认为。nginx＋php-cgi要比apache＋php-cli要好。但是要想达到好多好多倍，我看难。
上面所做对比，不考虑11nginx，配合10php-cgi是否合理，这个就nginx来说，肯定不是很合理的。
