coolpy7_benchmark

This is a simple MQTT benchmark tool written in Golang. The main purpose of the tool is to benchmark how many concurrent connections a MQTT broker could support.

QuickStart

$ git clone https://github.com/Coolpy7/coolpy7_benchmark.git
$ cd bin

//sub test
./go_build_cp7_bench_sub_go_linux -workers=4000000 -cid=tqy -topic=null -qos=0 -url=tcp://192.168.200.238:1883 -keepalive=60000s -clear=true

//pub test
./go_build_cp7_bench_pub_go_linux -cid=cp7 -clear=true -keepalive=300s -qos=0 -s=256 -topic=a/b/c -url=tcp://192.168.100.2:1883 -workers=500

Sub Benchmark

$ ./go_build_cp7_bench_sub_go_linux -h

  -workers int
        number of workers (default 100)

  -h                 help information
  -cid               client id start with this value profix + workers id [like: testclient0]
  -clear             clean session [default: true]
  -keepalive         keep alive in seconds [default: 300]
  -qos               subscribe qos [default: 0]
  -topic             topic subscribe, support %i variables
  -url               mqtt connect string [like: tcp://username:password@192.168.100.2:1883]
  -workers           mqtt connection clients count [default: 100]
