CPU性能测试工具-Unixbench

简介:

UnixBench是一个类unix系(Unix,BSD,Linux)统下的性能测试工具,一个开源工具,被广泛用与测试linux系统主机的性能。Unixbench的主要测试项目有:系统调用、读写、进程、图形化测试、2D、3D、管道、运算、C库等系统基准性能提供测试数据。unixbench一个基于系统的基准测试工具,不单纯是CPU 内存 或者磁盘测试工具。测试结果不仅仅取决于硬件,也取决于系统、开发库、甚至是编译器。

 

测试过程:

 

  1. make
  2. ./Run -c 1 -c 4 2
 Run [‐q | ‐v] [‐i ] [‐c  [‐c  …]] [test …]
说明:
    ‐q 运行quiet 模式

    ‐v 运行vobose 模式

    ‐i  每个测试运行count 次循环‐‐‐较慢测试使用/3,但是至少为1。默认为10(对较慢测试为3)

    ‐c  平行运行每个测试个拷贝,此选项可以指定多次,例如./Run ‐c 1 ‐c 4 命令,

    将会执行一个单流测试,和一个4流的测试

 

结果解析:

参数说明:

测试项目 测试内容
Dhrystone 该测试侧重字符串处理,没有浮点运算。结果受硬件设计和软件优化影响大
Whetstone 测试浮点运算速度和效率,其中包含几个典型的科学计算性能模块
Execl Throughput 测量 execl 每秒可执行的系统调用次数
File Copy 测试数据从一个文件传输到另一个文件的传输速率
Pipe Throughput 测试每秒一个进程将512字节写入管道并读取的次数
Pipe-based Context Switching 测试每秒两个进程通过一个管道交换一个不断增长的整数次数
Process Creation 测试每秒一个进程可以创建及收回子进程的次数
Shell Scripts 测试每秒进程可以并发获取一个 shell 脚本的 n 个副本的次数,n取值为1 2 4 8
System Call Overhead 测试进入和离开操作系统内核的开销,即执行系统调用的消耗
Graphical Tests 测试显卡2D和3D图形的大概性能,结果很视乎系统是否安装适当的驱动程序
