Nginx
有几个必需得Nginx调整。有人跟我说过，我禁用了gzip以保证比较公平。下面是它的配置文件/etc/nginx/nginx.conf：
user www-data;
worker_processes auto;
worker_rlimit_nofile 200000;
pid /var/run/nginx.pid;
events {
worker_connections 10000;
use epoll;
multi_accept on;
}

tcp_nodelay on;

open_file_cache_valid 300s;
open_file_cache_min_uses 2;
