Bonnie是一款极小的测试系统IO性能的工具,源代码公开.作者主页:

编译Bonnie极其简单,但是需要你安装了make及gcc (或cc)

 

# make Options are "make bsd" and "make SysV" - the default is "bsd". If you get messages about missing functions, try "make SysV." make Bonnie make[1]: Entering directory `/export/home/gqgai/bonnie' cc -O Bonnie.c -o Bonnie make[1]: Leaving directory `/export/home/gqgai/bonnie'

操作示例： 
os:redhat as 4.2

[root@ns ~]# mkdir bonnie [root@ns ~]# cd bonnie [root@ns bonnie]# tar zxvf bonnie.tar.gz [root@ns bonnie]# make Options are "make bsd" and "make SysV" - the default is "bsd". If you get messages about missing functions, try "make SysV." make Bonnie make[1]: Entering directory `/root/bonnie' cc -O     Bonnie.c   -o Bonnie make[1]: Leaving directory `/root/bonnie' 文件: bonnie.tar.gz 大小: 6KB 下载: 下载 [root@ns bonnie]# ./Bonnie -d /opt -s 512 -m billing-center File '/opt/Bonnie.8384', size: 536870912 Writing with putc()...done Rewriting...done Writing intelligently...done Reading with getc()...done Reading intelligently...done Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done...               -------Sequential Output-------- ---Sequential Input-- --Random--               -Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seeks--- Machine    MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU  /sec %CPU billing-  512 16447 79.5 44006 40.2  8467  9.9 15055 71.3 17480 13.3  50.3  1.1

解释说明：

这里Sequential Output指写入速度,Char指按字符方式写入,Block指按块方式写入,Rewrite指顺序改写速度(也就是数据修改)
Sequential Input指读取速度

CPU,指该操作占用的CPU资源.

此处写放速度为: 16447K/sec

-d scratch-dir

-s size-in-Mb

-m machine-label

-htmlIf you use this, Bonnie will generate a report in HTML form, as opposed to plain text. This is not all that useful unless you are prepared to write a table header.更多   http://www.textuality.com/bonnie/advice.html
