Linux测试CPU 整型算力和浮点数算力
1.sysbench：用于测试 CPU 整型算力
1.0 介绍
SysBench是一个模块化的、跨平台、多线程基准测试工具，主要用于评估测试各种不同系统参数下的数据库负载情况。它主要包括以下几种方式的测试：
- cpu性能
- 磁盘io性能
- 调度程序性能
- 内存分配及传输速度
- POSIX线程性能
- 数据库性能(OLTP基准测试)
目前sysbench主要支持 MySQL,pgsql,Oracle 这3种数据库。

- 测试 4 线程，20000 内的质数计算能力
(base) jupiter@dell:/software/sysbench-1.0.20$ sysbench cpu --cpu-max-prime=20000 --threads=4 --time=60 run
# 参数解释
--cpu-max-prime=20000 测试计算素数直到某个最大值(20000)所需要的时间
--threads=4 使用线程数为4
--time=60 重复次数为60次- 测试结果/Score : 1497.06
