HTTP服务器压力测试

HearyHTTPd进行压力测试。网上的压力测试工具很多,我测试了Apache benchmarkWebBench两款压力测试工具,并在台式机和实验室计算服务器上分别进行了压力测试,QPS分别约6400+、21000+和30000+。

HTTP服务器压力测试

1 Apache benchmark

1.1 简介

Apache benchmark

ab - Apache HTTP server benchmarking tool

ab is a tool for benchmarking your Apache Hypertext Transfer Protocol (HTTP) server. It is designed to give you an impression of how your current Apache installation performs. This especially shows you how many requests per second your Apache installation is capable of serving.

Apache benchmark是一款Apache提供的HTTP服务器压力测试工具,随Apache安装。

1.2 安装

1
sudo apt install apache2-utils

1.3 测试

我测试了我的HearyHTTPd,用1000个客户机并发请求10万次。

在我的实验室台式机上进行了测试:

  • CPU:Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz
  • 内存:单通道 8GB DDR4 2400Mhz
  • 通过WSL中的Ubuntu来测试Windows环境JRE下运行的hhttpd。

  • 测得结果平均每秒能处理6412个请求。
  • 多次测试能稳定在6000以上。
  • 测试中观察内存和CPU消耗无异常情况。
  • 其他影响因素:实验过程中,Windows Defender的Antimalware Service Executable进程的CPU使用率明显上升,约7~10%。

另外,我在实验室的新服务器上进行了测试:

  • CPU:2颗Intel(R) Xeon(R) Gold 6132 CPU @ 2.60GHz
  • 内存:512G(16根32G) ECC DDR4 2666Mhz

2 webBench

2.1 简介

GitHub地址:WebBench

Webbench是Radim Kolar在1997年写的一个在linux下使用的非常简单的网站压测工具。它使用fork()模拟多个客户端同时访问我们设定的URL,测试网站在压力下工作的性能,最多可以模拟3万个并发连接去测试网站的负载能力。官网地址:http://home.tiscali.cz/~cz210552/webbench.html
