再次声明，不是广告阿

比我的牛。。

hdparm  -Tt /dev/sda

/dev/sda:
Timing cached reads:   2636 MB in  2.00 seconds = 1316.23 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
Timing buffered disk reads:  184 MB in  3.00 seconds =  61.30 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device

cnhnln

你用的是什么硬盘？

/dev/hda:
Timing cached reads:   2620 MB in  2.00 seconds = 1309.92 MB/sec
Timing buffered disk reads:   84 MB in  3.06 seconds =  27.41 MB/sec

第二个测试很低，笔记本硬盘的瓶颈吧。

[root@cobranail ~]# hdparm -Tt /dev/sdb

/dev/sdb:
Timing cached reads:   1612 MB in  2.00 seconds = 805.95 MB/sec
Timing buffered disk reads:  166 MB in  3.01 seconds =  55.18 MB/sec

第一个测试没有什么意义
你的也不比我的快多少，你的才82而已

cnhnln

谁说没意义，俺的缓存有16M
PS：你的什么硬盘？

数据的实际参考价值不是很大。用bonnie++、iozone之类测试的结果才会更准确些
