sysbench

sysbench是一个开源的、模块化的、跨平台的多线程性能测试工具，可以用来进行CPU、内存、磁盘I/O、线程、数据库的性能测试。

安装 sysbench：

apt install -y sysbench

ICE-EVB 开发板测试：

• 测试线程：

  ```bash root@thead-910:/# ./sysbench --test=threads --num-threads=32 --thread-yields=100 --thread-lock=8 run sysbench 0.5: multi-threaded system evaluation benchmark

  Running the test with following options: Number of threads: 32 Random number generator seed is 0 and will be ignored

Threads started!

General statistics: total time: 2.9138s total number of events: 10000 total time taken by event execution: 93.1165s response time: min: 0.14ms avg: 9.31ms max: 82.38ms approx. 95 percentile: 32.83ms

Threads fairness: events (avg/stddev): 312.5000/14.83 execution time (avg/stddev): 2.9099/0.00

  换算：

  14.83/2.9099=5.1



其他测试项目：

- 测试CPU:

  ```bash
  root@thead-910:~# ./sysbench --test=cpu --cpu-max-prime=20000 --num-threads=2 run
  sysbench 0.5:  multi-threaded system evaluation benchmark

  Running the test with following options:
  Number of threads: 2
  Random number generator seed is 0 and will be ignored


  Primer numbers limit: 20000
