测试目的

由于K8s缘故涉猎go语言,发现golang的web框架很多,都号称高性能标杆;之前一直致力于c++高性能服务端框架研究,出于好奇,想单从性能层面客观比较一下go的众多web框架,另一方面也希望看看c++的实现与go语言实现之间究竟存在多大差异。

高性能服务框架评估指标很多,但一般来讲吞吐量与QPS是关键考量指标,吞吐量衡量带宽利用率,QPS主要考验框架调度性能(几乎所有可称之为“高性能”的服务框架都没有吞吐量问题,毕竟网络瓶颈很轻易就达到了)。由于是框架本身QPS测试,为了屏蔽http协议实现差异选择最精简的协议头(协议处理一般不会有锁,为cpu密集型),因此要求请求/返回报文尽可能小,本文测试基于http协议,返回空报文。

为了实现测试的第二个目的,特将一个自撸的c++服务框架作为c++实现的”砖头”,加入到对比测试中。此框架尚未开源,其高性能特性保障体现在如下设计上:

  • 跨平台实现socket多路复用,支持:poll、epoll、kqueue、port、select、IOCP等模型
  • 采用lock-free算法
  • 线程池设计
  • socket连接池
  • 多级任务队列
    ……

PS:
好吧,这样一来貌似更接近测试socket服务框架调度性能……
不要纠结keep-alive,因为wrk使用HTTP/1.1,默认都是keep-alive的

测试环境

环境设置

ulimit -n 2000

压测工具

wrk
由于环境限制,只能wrk客户端和待测试服务端在一台机器上运行

  • go语言web框架中gin、chi、echo性能相当,gin略显优势,iris实测效果不佳;
  • go语言与c++语言网络框架比较还是存在一定性能差距,但不是决定性的;
  • go语言整体资源耗用大,c++足够轻量高效;
  • go语言真的很易用且简洁!!就是三方依赖太多 ,拿来主义,问题排查那是相当酸爽… 当然,随着依赖包升级你会一直爽 :)
