近来想了解一下开发环境的IO性能，分别用dd/orion/iozone/bonnie++四种工具测试了一下
开发环境系统配置如下:
Intel SR1625 server, 2 CPU, 32GB内存, 用主板自带卡做了raid1+0，8个7200转SATA硬盘
操作系统是RHEL 5.3 64位
因为物理内存是32GB，因此整个过程都选用了60GB+的数据量来测试，以避免cache的影响
1. 首先用自带的dd命令先测一下, 块大小为8k
dd只能提供一个大概的测试结果，而且是连续IO而不是随机IO
读测试
# time dd if=/dev/sda2 f=/dev/null bs=8k count=8388608
8388608+0 records in
8388608+0 records out
68719476736 bytes (69 GB) copied, 516.547 seconds, 133 MB/s
real 8m36.926s
user 0m0.117s
sys 0m55.216s
写测试
# time dd if=/dev/zero f=/opt/iotest bs=8k count=8388608
8388608+0 records in
8388608+0 records out
68719476736 bytes (69 GB) copied, 888.398 seconds, 77.4 MB/s
real 14m48.743s
user 0m3.678s
sys 2m47.158s
读写测试
# time dd if=/dev/sda2 f=/opt/iotest bs=8k count=8388608
8388608+0 records in
8388608+0 records out
68719476736 bytes (69 GB) copied, 1869.89 seconds, 36.8 MB/s
real 31m10.343s
user 0m2.613s
sys 3m25.548s
2. 接下来用Oracle的orion工具来测一下
解压即可使用
# gzip orion_linux_x86-64.gz
测异步IO时需要libaio库
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64
# echo $LD_LIBRARY_PATH
:/opt/oracle/product/10.2.0/lib:/usr/lib64
创建配置文件mytest.lun,列出要测试的分区即可. 注意文件名前缀要跟下面的 testname一致
# vi mytest.lun
查看mytest.jun内容
# cat mytest.lun
/dev/sda2
先来个simple test
# ./orion_linux_x86-64 -run simple -testname mytest -num_disks 8
查看测试结果
# cat mytest_20081111_1431_summary.txt
ORION VERSION 11.1.0.7.0
Commandline:
-run simple -testname mytest -num_disks 8
This maps to this test:

Small IO size: 8 KB
Large IO size: 1024 KB
IO Types: Small Random IOs, Large Random IOs
Simulated Array Type: CONCAT
Write: 0%
Cache Size: Not Entered

Maximum Small IOPS=442 @ Small=40 and Large=0
Minimum Small Latency=14.62 @ Small=1 and Large=0
最大MBPS为56.97，最大IOPS为442
再测一下8k随机读操作
# ./orion_linux_x86-64 -run advanced -testname mytest -num_disks 8 -size_small 8 -size_large 8 -type rand &
看看结果
# cat mytest_20081111_1519_summary.txt
ORION VERSION 11.1.0.7.0
Commandline:
-run advanced -testname mytest -num_disks 8 -size_small 8 -size_large 8 -type rand
This maps to this test:
Test: mytest

Large Columns:, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16
Total Data Points: 38
Name: /dev/sda2 Size: 629143441920

Maximum Large MBPS=3.21 @ Small=0 and Large=13
Maximum Small IOPS=448 @ Small=38 and Large=0
Minimum Small Latency=15.16 @ Small=1 and Large=0
最大MBPS为3.21(这么低？？)，最大IOPS为448
再测一下1M顺序读操作, 失败了, 原因不明...
# ./orion_linux_x86-64 -run advanced -testname mytest -num_disks 8 -size_small 1024 -size_large 1024 -type seq
ORION: ORacle IO Numbers -- Version 11.1.0.7.0
mytest_20081114_1349
Test will take approximately 73 minutes
Larger caches may take longer
rwbase_run_test: rwbase_reap_req failed
rwbase_run_process: rwbase_run_test failed
rwbase_rwluns: rwbase_run_process failed
orion_warm_cache: Warming cache failed. Continuing
看看结果
# cat mytest_20081111_1620_summary.txt
ORION VERSION 11.1.0.7.0
Commandline:
-run advanced -testname mytest -num_disks 8 -size_small 1024 -size_large 1024 -type seq
This maps to this test:
Test: mytest
Small IO size: 1024 KB
Large IO size: 1024 KB
IO Types: Small Random IOs, Large Sequential Streams
Number of Concurrent IOs Per Stream: 4
Force streams to separate disks: No
Simulated Array Type: CONCAT
Write: 0%
Cache Size: Not Entered
Duration for each Data Point: 60 seconds
没结果，失败
3. 用iozone来测一下
安装
# tar -xvf iozone3_345.tar
# make linux-AMD64
指定64G的文件，只测read/reread和write/rewrite，记录大小从4k-16k.同时生成一个excel文件iozone.wks
# ./iozone -Rab iozone.wks -s64G -i 0 -i 1 -y 4k -q 16k

4. 最后用bonnie++测一下
安装
# export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64
# ./configure

随机读写: 176.7次/s，CPU占用率0%
后两项全是++ (没结果?)
结论:不同测试工具构建出来的测试环境不同，侧重点也不一样，得到的结果可能相差比较大。
MBPS:
dd和iozone比较接近，读写分别是130+和70+。
orion读57左右，写没测(会删掉分区内所有文件!)
bonnie++按块读是130左右，写是35左右；按字符读是56左右，写是52左右
