由于Bonnie存在一些众所周知的问题,比如>2G的文件支持.
Russell Coker (russell@coker.com.au) 开发了一套新的代码,用以支持>2G的文件等.
得到Tim Bray (tbray@textuality.com)的许可之后,Russell把他的软件命名为bonnie++,在网上发布,并开始流行起来.
目前的版本已经更新到了1.03a,你可以到以下地址下载:
http://www.coker.com.au/bonnie++/
你也可以点击这里下载,这个版本需要编译,如果你没有编译环境,可以点击这里下载我编译好的,适用于SUN Solaris环境(Solaris8测试通过)

Bonnie++ 与 bonnie的区别主要是:

我简单介绍一下Bonnie++的编译及使用:
1.编译
你需要把以上下载的源码编译以后才能使用,如果你没有编译环境,可以点击这里下载我编译好的,适用于SUN Solaris环境(Solaris8测试通过)
当然你需要安装make,及gclearcase/" target="_blank" >cc等必要编译器.在编译过程中,如果遇到以下错误,可能是因为你没有设置正确的环境变量
$ ./configure
grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .
grep: illegal option -- q
Usage: grep -hblcnsviw pattern file . . .
checking for g++... g++
checking for C++ compiler default output... a.out
checking whether the C++ compiler works... configure: error: cannot run C++ compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
|
设置环境变量后继续编译,一般可以成功.

# ./configure

编译完成之后会生成bonnie++,可以用来测试了.
2.下面是一些测试结果

b. EMC CLARiiON CX500 测试数据
这个是在我禁用了写Cache以后的测试数据:
4块盘的Raid1+0测试:
# ./bonnie++ -d /eygle -u root -s 4096 -m jump
Using uid:0, gid:1.
File size should be double RAM for good results, RAM is 4096M.
# ./bonnie++ -d /eygle -u root -s 8192 -m jump

对比这两个结果我们发现(单位K/sec):
| |
字符写 |
Block写 |
字符读 |
Block读 |
| Raid10 |
12,647 |
13,414 |
33,636 |
146,503 |
| Raid5 |
10,956 |
10,771 |
34,169 |
158,861 |
| Diff |
1,691 |
2,643 |
-533 |
-12,358 |
我们看到,在直接读写上,写Raid10会略快于Raid5;而在读取上,Raid5会略快于Raid10,这符合我们通常的观点.
这里需要提一下的是,通常我们建议把RedoLog file存放在Raid10的磁盘上,因其具有写优势.
