Slow Loading/100% CPU For Thumbnails

[hmfaysal]

I am having the same problem, for the time being solved it with aggressive nginx proxy caching

Code:

    # Images / Thumbnails
    location ~ ^/Items/.*/Images/ {
        proxy_pass http://127.0.0.1:8096;

        proxy_http_version 1.1;
        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_set_header X-Forwarded-Proto $scheme;

        # --- disk cache ---
        proxy_cache          jfimg;
        proxy_cache_valid    200 1y;          # honour upstream max-age if present
        proxy_cache_revalidate on;
        proxy_cache_lock    on;              # avoid stampedes
        proxy_cache_key      "$scheme$proxy_host$request_uri";
        add_header          X-Cache-Status $upstream_cache_status always;

        # --- browser cache ---
        expires 1y;
        add_header Cache-Control "public, immutable";

        # Small buffers are fine for images; leave buffering on for speed
        proxy_buffering      on;
        proxy_buffer_size    64k;
        proxy_buffers        8 64k;
        proxy_busy_buffers_size 256k;
    }

I am well aware this is not a permanent solution. But this has to do for now till we get a better solution. Open to any suggestion
