TL; DR
各语言原生 HTTP 高并发测试性能
尽量排除其他因素的影响，例如各语言文件读写能力
结论: Golang > Deno > Nodejs > Python(异步IO) > Dart(异步IO) > PHP
不同语言实现的高并发测试
测试参数:
持续请求 10 秒
并发量 100
服务的的操作:
返回一个 test_file.js 文件的内容
测试脚本
> siege -c 100 -t 10s http://127.0.0.1:3000/

声明
这个测试并不是标准的基准测试，也不是都很熟悉这些语言。
而且是在服务的和客户端在同一台机器，有竞争状态不是很准确。
如有错误，欢迎指出。
