压缩 uwsgi-nginx 和 nginx 负载均衡器之间的流量

我有 7 个 nginx 网络服务器运行一个 python 应用程序并通过 uwsgi 和套接字文件将其提供给 nginx，在这 7 个网络服务器前面有一个 nginx 负载均衡器，从负载均衡器传到公共的流量被正确压缩，导致传出流量只有~20Mbps，但是从网络服务器传出到负载均衡器的流量由于某种原因没有被压缩，导致负载均衡器的总传入流量（来自服务器子网接口）为 400Mbps，每个网络服务器的传出流量约为 70Mbps。

是否应以与在负载均衡器（其工作的地方）上启用 gzip 压缩相同的方式启用它？这里的配置是否有所不同？

嘿伙计，像这样使用 gzip 压缩

    gzip on;
    gzip_http_version 1.1;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_proxied any;
    gzip_types text/plain text/html text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript text/x-js image/gif image/jpeg application/atom+xml application/rss+xml text/x-component image/png image/tiff image/vnd.wap.wbmp image/x-icon image/x-jng image/x-ms-bmp image/svg+xml image/webp application/font-woff application/msword application/pdf;
    gzip_buffers 16 8k;
    gzip_disable "MSIE [1-6]\.(?!.*SV1)";
