Время отклика

[Fixid]

Есть фронтенд с NGINX. При заходе на сайт
до начала загрузки (т.е. время
соединения ) около 30 секунд, потом все
нормально, контент загружается  быстро.
Как можно уменьшить время отклика?

user  nginx;
worker_processes  2;
worker_rlimit_nofile 100000;

error_log   /var/log/nginx/error.log;
#error_log  /var/log/nginx/error.log  notice;
#error_log  /var/log/nginx/error.log  info;

pid        /var/run/nginx.pid;


events {
    worker_connections  5024;
    use epoll;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

"$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    include /etc/nginx/conf.d/*.conf;

    server {
        listen 80 default;
rewrite ^ https://www.test.com/;
    }
}


SSL:

server {
    listen       443 default;
    server_name  www.test.com ;

    ssl                  on;

    if ($host = "test.com" ) {
    rewrite ^ https://www.test.com/;
}
    location / {

}
