Nginx Reverse Proxy benötigt ca. 15 Sekunden zum Laden der Seite

Question

Ich verwende nginx zum ersten Mal und weiß daher nicht wirklich, ob das zu erwarten ist. Ohne nginx sollte die Seite normalerweise in weniger als 5 Sekunden starten. Ich habe die Fehlerprotokolle überprüft und es scheinen keine Fehler aufzutreten.

Hier ist meine Nginx-Konfiguration:

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name localhost;
        return 301 https://$server_name$request_uri;

        root /var/www/html;
        # Add index.php to the list if you are using PHP
        index index.html index.htm index.nginx-debian.html;
        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }


server {
        # SSL Configuration
        listen 443 ssl http2 default_server;
        listen [::]:443 ssl http2 default_server;
        server_name localhost;
        include snippets/self-signed.conf;
