我正在MediaWiki中运行三个负载均衡的Mongrel进程。 我有其他的Web应用程序安装在不同的目录。 我已经尝试将其剥离到最低限度的服务器，它只能转发给代理。 这不会有什么区别，通过Apache是显着和明显慢。
Mongrel进程是由mongrel_service gem创build的服务，它们在registry中的起始行如下所示：
"c:/ruby/bin/mongrel_service.exe" service single -e production -p 8005 -a 0.0.0.0 -l "log/authentication.log" -P "log/mongrel.pid" -c "c:/track" -t 0 -r "public" -n 1024 --prefix "/track"
什么可能导致这种放缓？ 如何解决问题？
我已经看到，改变“本地主机”到“127.0.0.1”，大大缩短了mod_proxy的时间。 但我不知道为什么。 我真的很想看到答案。 我无法想象需要整整一秒来解决本地主机。
