环境： SUN 4路4核CPU。16G内存。4 块SCSI 140G硬盘。MySQL 企业版 5.1.30。
简单的测试了一下，可能具体情况下对应的性能有其他差别。
以下是具体的测试步骤。
1. 安装。先用fdisk 工具在第四块硬盘上分好区，每个区30G。对应的文件系统分别是EXT3, XFS, GFS.
如下：
[root@X-39 ~]# mkfs.ext3 /dev/sdd5
mke2fs 1.39 (29-May-2006)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
3662848 inodes, 7325632 blocks
366281 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
224 block groups
32768 blocks per group, 32768 fragments per group
16352 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@X-39 ~]# mkfs.xfs /dev/sdd6
meta-data=/dev/sdd6 isize=256 agcount=4, agsize=1831408 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=7325632, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=3576, version=2
= sectsz=512 sunit=0 blks, lazy-count=0
realtime =none extsz=4096 blocks=0, rtextents=0
由于我们只用测试单机的性能，那么 LOCK 的协议就用 lock_nolock,否则就用lock_dlm.
[root@X-39 ~]# gfs_mkfs -t nfs_cluster:gfs1 -p lock_nolock -j 8 /dev/sdd7
This will destroy any data on /dev/sdd7.
It appears to contain a gfs filesystem.
Are you sure you want to proceed? [y/n] y
Device: /dev/sdd7
Blocksize: 4096
Filesystem Size: 7062824
Journals: 8
Resource Groups: 108
Locking Protocol: lock_nolock
Lock Table: nfs_cluster:gfs1
Syncing...
All Done
[root@X-39 opt]# mount -t ext3 /dev/sdd5 /opt/ext3
[root@X-39 opt]# mount -t xfs /dev/sdd6 /opt/xfs
[root@X-39 opt]# mount -t gfs /dev/sdd7 /opt/gfs
2. 建立MySQL 表空间。
分别在3 个分区上建立 3 个 20G 的表空间。
3. 分别测试插入性能和读写混合的性能。
a. 插入性能对比：
EXT3 文件系统。
[root@X-39 bin]# time ./sysbench --test=oltp --mysql-host=localhost --mysql-user=root --mysql-table-engine=innodb --mysql-db=test --oltp-table-size=10000000 --db-driver=mysql prepare
sysbench 0.4.10: multi-threaded system evaluation benchmark
Creating table 'sbtest'...
Creating 10000000 records in table 'sbtest'...
real 3m44.272s
user 0m0.088s
sys 0m0.084s
XFS 文件系统。
[root@X-39 bin]# time ./sysbench --test=oltp --mysql-host=localhost --mysql-user=root --mysql-table-engine=innodb --mysql-db=test --oltp-table-size=10000000 --db-driver=mysql prepare

GFS 文件系统。
[root@X-39 bin]# time ./sysbench --test=oltp --mysql-host=localhost --mysql-user=root --mysql-table-engine=innodb --mysql-db=test --oltp-table-size=10000000 --db-driver=mysql prepare

Creating 10000000 records in table 'sbtest'...
real 3m44.084s
user 0m0.000s
sys 0m0.056s
b. 读写混合性能对比：
总共80W个请求，一个事务里面10条Queries.
EXT3 文件系统。
[root@X-39 bin]# time ./sysbench --test=oltp --mysql-host=localhost --mysql-user=root --mysql-table-engine=innodb --mysql-db=test --oltp-table-size=10000000 --db-driver=mysql --num-threads=300 --oltp-index-updates=10 --max-requests=800000 run
