armyant(行军蚁)

mqant压力测试工具

简介

armyant是从http压力测试工具hey改装而成。

hey只支持http接口的压力测试而armant可以自定义压测协议。

目前默认实现了http，mqtt两种协议的压力测试工具

依赖模块

go get github.com/eclipse/paho.mqtt.golang

使用方法

armyant无命令行工具,目前需要通过源码编译执行

http压测

入口 http_task.go

具体实现: http_task/work.go

mqtt压测

入口 mqtt_task.go

具体实现 mqtt_task/work.go

可以通过修改work.go代码来灵活更改具体的压测内容

操作系统最多文件打开限制

默认情况下普通操作系统都会限制系统同时打开的文件数量，mac系统默认是256. 如果不放开该限制armyant发出更多并发请求。

mac打开限制方式

linux打开方式

自己百度

paho.mqtt.golang 内存怪兽

默认的paho.mqtt.golang客户端是内存怪兽，每一个mqtt客户端都会消耗巨大内存 gopath/src/github.com/eclipse/paho.mqtt.golang/client.go

c.messageIds = messageIds{index: [65535]Token{}} 默认会创建65535个Token

改为

c.messageIds = messageIds{index: [10]Token{}}

gopath/src/github.com/eclipse/paho.mqtt.golang/messageids.go

messageids.go 文件也需要做对应修改

mqant的压测参数

系统硬件:

MAC电脑2核,16G内存,固态硬盘

进程:

1. mqantserver 进程一个
2. armyant 压测进程一个

压测结果:

每一个连接每秒发出1个远程调用请求
能达到的最大并发数为:5000

内存使用:

mqantserver进程 131M aryant 进程 191m

如只连接不发远程调用请求可以轻松上万并发

本次压测结果并不严谨,所用设备是自己的MAC电脑，同时还开启了很多编译器。 压测工具与测试进程也都在同一台机器,压测瓶颈主要在CPU性能上
