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 和一个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，从负载均衡器向公众发出的流量被正确压缩，导致只有~20Mbps的传出流量，但是由于某种原因从网络服务器和负载均衡器出来的流量没有被压缩，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Web 服务器可以承受大约 70Mbps 的传出流量。

是否应该像在 laod 平衡器上启用 gzip 压缩一样启用它（它在哪里工作）？这里有一些不同的配置吗？
