Is it still slow if you expose a port on the app container and access it directly?

I changed to nextcloud:apache and the same problem

by the way, I use reverse proxy

    location /nextcloud/ {
        proxy_pass_header Authorization;
        proxy_pass http://ip:8080/;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #proxy_http_version 1.1;
            #proxy_set_header Connection "";
            #proxy_buffering off;
        client_max_body_size 0;
        #proxy_redirect off;
            #proxy_ssl_session_reuse off;
            #proxy_connect_timeout 600;
            #proxy_send_timeout 600;
            #proxy_read_timeout 600;
            #send_timeout 600;
    }

Yes, I’m asking if it’s still slow without the reverse proxy?

Yes, the same problem when access directly when use apache image

Anyone can tell me how to find out the reason?
