sysbench

sysbench是给予LuaJIT的多线程性能测试工具。通常用于测试数据库性能，但是也可以创建抽象的负载负载用于测试多种场景:

  • oltp_*.lua 一系列OLTP类的数据库压测
  • fileio 文件系统层对压测
  • cpu 简单的CPU压测
  • memory 内存访问压测
  • threads 基于线程的调度器压测
  • mutex 一个POSIX mutex压测

安装

sysbench测试案例提供了多种平台的安装方法，例如，可以通过EPEL

sysbench GitHub文档提供方法：

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
sudo yum -y install sysbench

源代码安装

压测案例

  • 测试8个cpu的虚拟机性能
sysbench cpu --threads=8 --time=300 --cpu-max-prime=100000 run

cpu-max-prime 寻找最大素数

time 持续时间，默认是--time=0表示不限制时间

输出举例

sysbench 1.0.9 (using system LuaJIT 2.0.4)

Running the test with following options:
Number of threads: 8
Initializing random number generator from current time


Prime numbers limit: 100000

Initializing worker threads...
