Question

我们的生产服务器有Ubuntu 9.x，内存8GB，HDD 250Gb使用nginx作为webserver。我们目前在高峰时段遇到性能问题（1000次/秒）我希望服务器可以服务1000个请求/秒，有人可以告诉我应该在nginx配置上更改什么。感谢

这里是nginx conf

如果不分析系统，很难说...你必须首先找到大部分时间花在请求上的地方。它不常见的是ngingx或apache是问题的原因。

考虑到你发布了一个ruby-on-rails标签，我想你在nginx后面有一个rails应用程序...更有可能是rails应用程序导致问题。我要检查的第一件事是数据库查询。检查日志以查找慢查询并尝试找到一种方法使它们更快...索引始终是一个很好的开始....

如果你找不到任何东西，可以尝试使用工具作为新的遗物，找到你的性能问题......

nginx配置可以提供1000个请求/秒
