各种语言web性能简单对比测试

忽然想比较一下 python nodejs go 的web 响应，就简单的写了个性能对比测试。

测试目标：
1 . i5 4核 32G 同一机器 linux
2. 用python（flask线程模式） nodejs go 分别写了简单的 echo 服务

测试工具：
wrk

服务器清单：

python  flask      http://192.168.0.208:5050/
nodejs  express    http://192.168.0.208:5056/
go      server     http://192.168.0.208:5057/

测试脚本：

wrk -c100 -t10 -d30s  http://192.168.0.208:5050/
wrk -c100 -t10 -d30s  http://192.168.0.208:5056/
wrk -c100 -t10 -d30s  http://192.168.0.208:5057/

wrk -c1000 -t10 -d30s  http://192.168.0.208:5050/
wrk -c1000 -t10 -d30s  http://192.168.0.208:5056/
wrk -c1000 -t10 -d30s  http://192.168.0.208:5057/

测试结果：

结论：

1. 100 终端时：python 延时最大，与另外两个相差一个数量级， nodejs go 差不多。 Req/Sec 比例分别是 0.13 ： 4：13 ， go能大大 13k/s
2. 1000 终端时： nodejs 和 go 的延时增加，但还是明显优与 python , Req/Sec 保持稳定 python 最低，nodejs ：go 3:12 go的峰值 79k/s
3. 在高并发web服务中首选 go ， nodejs 次之 python 最弱

ps: 以上结论未考虑开发效率，人员薪资成本等因素
