Nginx有多层proxy_pass减速？

Question

我正在使用单个nginx.exe设置来执行多个proxy_pass，但它似乎导致实际服务器接收消息的延迟。这就是我的意思：Nginx Load Balancer - ＆gt;上游到Nginx主服务器上游到 - ＆gt;子服务器。如果需要扩展，我计划多个主服务器。当我测试它时，消息通过，但我必须等待一下。至少1分钟。我不确定我需要在配置文件中更改哪些设置才能使其更加即时。我尝试使用它自己的配置文件运行不同的Nginx.exe实例，但它仍然会导致相同的延迟。所有这些都在一台机器上进行测试。 tcp和http代理都会导致速度减慢。

我的配置文件：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;
