1，关于mqtt-benchmark

有两个github 项目：
使用的是这个，进行基准测试，带vendor 文件夹。展示的结果好看些。
https://github.com/krylovsk/mqtt-benchmark

一个日本人写的项目，没有 vendor，结果没有格式化。

2，使用

下载
https://github.com/krylovsk/mqtt-benchmark
里面少了一个 websocket的包。需要使用 vendor 工具补齐。

go get golang.org/x/net/websocket

#安装
go get -u github.com/kardianos/govendor
go install github.com/kardianos/govendor

进入工程目录 

#初始化
govendor init
#加入本地 vendor目录当中。
govendor add +external
#查看生成列表。
govendor list

查看list 安装

$ govendor list
pv  github.com/GaryBoone/GoStats/descriptive_statistics_demo    
pv  github.com/GaryBoone/GoStats/regression_demo                
 v  github.com/GaryBoone/GoStats/stats                          
 v  github.com/eclipse/paho.mqtt.golang                         
 v  github.com/eclipse/paho.mqtt.golang/packets                 
pv  github.com/eclipse/paho.mqtt.golang/samples                 
 v  golang.org/x/net/websocket                                  
pl  github.com/krylovsk/mqtt-benchmark                              
  m GoStats/stats                      

运行测试：

./mqtt-benchmark -broker="tcp://localhost:1883" -clients=300 -count=100 -size=10 -quiet=true -topic="/test" 

结果：
