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。

"short" variables; ditto for the ones below)

int Arithmetic Test (int)

long Arithmetic Test (long)

float Arithmetic Test (float)

double Arithmetic Test (double)

dc Dc: sqrt(2) to 99 decimal places (runs

"looper 30 dc < dc.dat", using your system's copy of "dc")

hanoi Recursion Test -- Tower of Hanoi

grep Grep for a string in a large file, using your system's

copy of "grep"

sysexec Exercise fork() and exec().

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。
