UNIXBENCH测试

UNXIBENCH5

一、            概述

   UNIXBENCH也是linux、unix测试系统基准性能的经典工具，UNIXBENCH测试包含了系统调用、读写、进程、2D、3D、管道、运算、C库等系统基准性能，它的优点在于提供了对系统性能的一种评价体系，为系统评分，如此方便对系统作对比测试；但UNIXBENCH在网络性能测试欠缺。

二、            测试内容

   unixbench5测试内容包含了system、2d、3d、misc测试项。system测试系统的一些基本功能；2d测试2D图形加速；3d测试3D加速；misc测试诸如字符，整型等测试。详情见下面。

三、           安装

   unixbench5包含system和graphic测试，如果你需要测试graphic，则需要修改Makefile,不要注释掉"GRAPHIC_TESTS = defined，同时需要系统提供x11perf命令gl_glibs库。

   进入源包，执行

   make

四、           快速使用

◆  执行system测试方法：Run

◆  执行graphic测试方法：Run graphics

◆  执行system,graphics测试方法：Run gindex

 

五、           详细使用方法

1.   Run用法

    Run [ -q | -v ] [-i <n> ] [-c <n> [-c <n> ...]] [test ...]

选项说明：

-q 

不显示测试过程

-v

显示测试过程

-i <count>

执行次数，最低3次，默认10

-c <n>

每次测试并行n个copies（并行任务）

备注：-c选项可以用来执行多次，如：

   Run -c 1 -c 4表示执行两次，第一次单个copies,第二次4个copies的测试任务。

test：

arithmetic      Runs arithoh, short, int, long, float, double,

                    and whetstone-double

   dhry            Alias for dhry2reg

   dhrystone       Alias for dhry2reg

   whets           Alias for whetstone-double

   whetstone       Alias for whetstone-double

   load            Runs shell1, shell8, and shell16

   misc            Runs C, dc, and hanoi

   speed           Runs the arithmetic and system groups

   oldsystem       Runs execl, fstime, fsbuffer, fsdisk, pipe, context1,

                    spawn, and syscall

   system          Runs oldsystem plus shell1, shell8, and shell16

   fs              Runs fstime-w, fstime-r, fstime, fsbuffer-w,

                    fsbuffer-r, fsbuffer, fsdisk-w, fsdisk-r, and fsdisk

   shell           Runs shell1, shell8, and shell16

 

   index           Runs the tests which constitute the official index:

                    the oldsystem group, plus dhry2reg, whetstone-double,

                    shell1, and shell8

                    See "The BYTE Index" below for more information.

   graphics        Runs the tests which constitute the graphics index:

                    2d-rects, 2d-ellipse, 2d-aashapes, 2d-text, 2d-blit,

                    2d-window, and ubgears

   gindex          Runs the index and graphics groups, to generate both

                    sets of index results

 

   all             Runs all tests

 

 

2.   测试说明

   对于多cpu系统的性能测试策略，需要统计单任务,多任务及其并行的性能增强。

以4个cpu的PC为例，需要测试两次，4个CPU就是要并行执行4个copies，

      Run -q -c 1 -c 4

3.   测试结果：

4.结果分析

      从上面的测试结果可以看出，但个并行的任务的得分为171.3,4个并行任务的得分为395.7。对比测试时需要关注这个值。

六、           高级用法

      unixbench也是一种灵活的测试框架，测试人员可以根据需求添加测试项。
