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

nginx配置文件：
#user nobody; worker_processes 4; error_log logs/error.log; events { use epoll; worker_connections 5120; } http { include mime.types; default_type application/octet-stream; sendfile on; #tcp_nopush on; keepalive_timeout 65; server { listen 80; server_name xxx.xxx.xxx.xxx; root /var/www/html; location / { index index.php index.html index.htm; } error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name; include fastcgi.conf; } location /hello { default_type 'text/plain'; content_by_lua 'ngx.say("hello")'; } location ~ \.cgi$ { fastcgi_pass 127.0.0.1:9001; fastcgi_index index.cgi; fastcgi_param SCRIPT_FILENAME fcgi$fastcgi_script_name; include fastcgi.conf; } } }
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。
