Apache V Nginx - 静态文件结果

Apache V Nginx - 静态文件结果

我使用 ab（ab -c50 -t5s）对同一台服务器上的 Apache V Nginx 静态文件进行基准测试。

Apache 在每秒处理 200 个请求时 CPU 占用率会很高，而 Nginx 在每秒处理 5211 个请求时 CPU 占用率约为 25%。

Apache 没有发生交换，因此不存在内存不足的问题。

我知道 Nginx 和 Apache 都有大量不同的配置，但 Nginx 落后 Apache 如此之多简直令人难以置信。

事实上太荒谬了，我认为我错过了 Apache 的一些东西。

有什么想法从哪里开始吗？

以下是 ab 结果：

答案1

此岗位现已不再存在。

我发现这不是标准的 Apache 设置，而扩展的 mod_security 规则才是问题所在。
