049-Kong1.4 vs SC Gateway2.2 vs Zuul1.3 性能测试

这是坚持技术写作计划(含翻译)的第49篇,定个小目标999,每周最少2篇。

本文主要对比常见API网关(kong 1.4,springcloud gateway 2.2, zuul 1.3)的性能测试(未涉及service mesh、traefik和envoy)

下载测试代码

$ git clone https://github.com/anjia0532/gateway-kong-zuul.git
$ cd gateway-kong-zuul
$ mvn clean package 
复制代码

或者从github下载我打包好的

$ wget https://github.com/anjia0532/gateway-kong-zuul/releases/download/0.0.1-SNAPSHOT/sc-gateway-0.0.1-SNAPSHOT.jar
$ wget https://github.com/anjia0532/gateway-kong-zuul/releases/download/0.0.1-SNAPSHOT/web-0.0.1-SNAPSHOT.jar
$ wget https://github.com/anjia0532/gateway-kong-zuul/releases/download/0.0.1-SNAPSHOT/zuul-0.0.1-SNAPSHOT.jar

endpoint

endpoint 描述
/api/ping 无入参,固定返回 "ok"
/api/echo?str=xx 入参str,返回str
/api/random-sleep?str=xx 入参str,随机sleep100毫秒-10秒,并返回str

启动服务

命令 端口 描述
java -jar sc-gateway-0.0.1-SNAPSHOT.jar 7080 SpringCloudGateway
http://localhost:7080/test/api/*
java -jar web-0.0.1-SNAPSHOT.jar 8080 SpringMVC
http://localhost:8080/api/*
java -jar zuul-0.0.1-SNAPSHOT.jar 6080 Zuul
http://localhost:6080/test/api/*
curl -i -X POST --url http://localhost:8001/services/ --data 'name=test' --data 'url=http://localhost:8080'

curl -i -X POST --url http://localhost:8001/services/test/routes --data 'paths[]=/test'
9000 Kong
http://localhost:8000/test/api/*

安装 wrk

$ git clone https://github.com/wg/wrk
$ make
复制代码

防止缓存,创建随机请求,注意第6行,在请求8080,web,项目时,没有路由 /test 信息,

wrk.method = "GET";
wrk.body = "";

request = function()
        ip = tostring(math.random(1, 255)).."."..tostring(math.random(1, 255)).."."..tostring(math.random(1, 255)).."."..tostring(math.random(1, 255))
        path = "/test/api/echo?str=" .. ip
        return wrk.format(nil, path)
end
复制代码

注意,我这是在vagrant+virtualbox里运行的,配置是2U4G,详见 Vagrantfile

运行三次,取最后一次的结果(除web项目一直启动外,其余随用随启,用完即停)

从QPS看 直连>Kong>Spring Cloud Gateway>Zuul

从内存和CPU看 直连肯定没有额外消耗,次之是Kong,然后是SC Gateway,最差的是Zuul

从管理的易用性看,Kong因为其便捷的插件体系及现有的插件生态完胜其余几样。

综合来看,建议使用Kong作为API网关。
