测试环境：
nginx 1.4.2 运行在 xxx.xxx.xxx.xxx（内网IP）
Intel(R) Xeon(R) CPU E5620 @ 2.40GHz

php-fpm配置：
pm = dynamic
pm.max_children = 200
pm.start_servers = 100
pm.min_spare_servers = 100
pm.max_spare_servers = 150
 

nginx配置文件：

#user nobody;

use epoll;
worker_connections 5120;
}
http {
include mime.types;
default_type application/octet-stream;

}
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
location ~ \.php$ {

}
location /hello {

}
}
 

c语言的fcgi源码：

#include <fcgi_stdio.h>

int main() {
while( FCGI_Accept() >= 0 ) {
printf( "Status: 200 OK\r\n" );
printf( "Content-Type: text/html\r\n\r\n" );
printf( "world\n" );
}
return 0;
}
gcc -lfcgi -Wall world.c -o world.cgi
spawn-fcgi -p 9001 -F 100 -u nobody -f /var/www/world.cgi
 

ab运行在内网另外一台服务器，不使用keepalive。

结论：

nginx-lua是相当的快……性能与比静态html还要牛X。

另外，并发100太小了， 完全没有发挥出来html和lua的性能，不过，上面的数据还是有一定的参考价值的。
