Nginx 提供图像服务非常慢

Question

我目前正在使用 AWS 和 Nginx 作为前端服务器部署一个简单的 django 网站。我的网站有许多平均大小为 400kb 的图像，我想在较慢的连接上尽快加载它们。但加载需要很长时间。

我看到了这个邮政但这没用。我找不到其他办法，只能手动压缩图片，但这肯定会降低图片质量，看起来很糟糕。

nginx.conf

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    sendfile_max_chunk 512;
    # server_tokens off;

    server_names_hash_bucket_size 128;

    # server_name_in_redirect off;

    include /etc/nginx/mime.types;
    default_type application/octet-stream;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
    ssl_prefer_server_ciphers on;

    gzip_comp_level 9;

    # gzip_http_version 1.1;
    gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

我的项目配置文件（已启用站点）

server {
    listen 80;
    server_name www.example.com example.com;

    location / {
        include proxy_params;
        proxy_pass http://unix:/path/to/app.sock;
    }
    location /static/ {
        gzip_static on;
        autoindex on;
        alias /home/ubuntu/myproject/static/;
    }
}
