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
