title: Nginx loading images very slow
body: <p>I am trying to load some high resolution images with Jpeg format and specs are 300dpi, 5000 x 5000 resolution in Django production. 
  Following are my nginx settings at digitalocean:</p>
  
  <pre><code>upstream app_server {
      server 127.0.0.1:9000 fail_timeout=0;
  }
  
  server {
      listen 80 default_server;
      listen [::]:80 default_server;
  
      root /home/django/django_project;
      index index.html index.htm;
  
      client_max_body_size 4G;
      server_name localhost;
  
  
      keepalive_timeout 5;
  
      # Your Django project's media files - amend as required
      location /media  {
          alias /home/django/django_project/media/;
      }
  
      # your Django project's static files - amend as required
      location /static/django_project/ {
          alias /home/django/django_project/static/django_project/; 
      }
      # Django static images
      location /static/django_project/images {
          alias /home/django/django_project/static-only/django_project/images/;
      }
  
  
      # Proxy the static assests for the Django Admin panel
      location /static/admin {
         alias /usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
      }
  
      location / {
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header Host $http_host;
          proxy_redirect off;
          proxy_pass http://app_server;
      }
  }
