NGINX NODE Socket滞后了一段时间，并且用户流程确实很高

Question

我们有一个带有Laravel和Node Socket.io的NGINX服务器 我不知道为什么，但是一段时间后变得越来越迟钝。

那是为什么？ 多数民众赞成在套接字的NGINX设置

server {
    server_name s.example.com;
    listen 443 ssl;

    ssl_certificate /etc/letsencrypt/live/s.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/s.example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/s.example.com/fullchain.pem;
    include /etc/nginx/snippets/ssl.conf;

    client_max_body_size 20M;

    location / {
            proxy_pass http://127.0.0.1:2053;
            proxy_http_version 1.1;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-NginX-Proxy true;
            proxy_set_header X-Forwarded-Proto https;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Host $http_host;
            proxy_redirect off;
            #proxy_buffering off;
            #proxy_buffers 8 2m;
            #proxy_buffer_size 10m;
            #proxy_busy_buffers_size 10m;
            #proxy_read_timeout 86400;
    }

}

就是网站

server {
    server_name www.example.com;
    listen 443 ssl;

    ssl_certificate /etc/letsencrypt/live/www.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/www.example.com/privkey.pem;
    ssl_trusted_certificate /etc/letsencrypt/live/www.example.com/fullchain.pem;
    include /etc/nginx/snippets/ssl.conf;

    root /var/www/example.com/site/public;
    index index.php index.html index.htm;

    try_files $uri $uri/ /index.php$is_args$args;

    large_client_header_buffers 8 32k;

    location ~ /.well-known {
            allow all;
    }

    location ~ \.php$ {
            #try_files $uri = 404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
            fastcgi_index index.php;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include fastcgi_params;
    }

}

我不知道，为什么网站一段时间后会滞后。

用户的使用过程也越来越高。 当我打开网站时，CPU，RAM和GPU上升了10％左右

htop上的“我的服务器”显示所有内容的0％，那是什么都没有。内核只有很少的峰值达到5-10％的时间，仅此而已。
