Compactar tráfego entre o balanceador de carga uwsgi-nginx e nginx

Question

Eu tenho 7 servidores web nginx executando um aplicativo python e servindo-o no nginx via uwsgi e um arquivo de soquete, em frente a esses 7 servidores Web existe um balanceador de carga nginx, o tráfego que sai do balanceador de carga para o público é compactado corretamente resultando em apenas ~ 20Mbps de tráfego de saída, no entanto o tráfego que sai dos servidores da Web e do balanceador de carga por algum motivo não é comprimido resultando no balanceador de carga ter um tráfego total de entrada de 400Mbps e cada um dos servidores da web para ter cerca de 70 Mbps de tráfego de saída.

A compressão gzip deve ser ativada da mesma forma que foi ativada no balanceador de laod (onde funciona)? é alguma configuração diferente aqui?

Hey man use compactação gzip assim

    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)";
