比我的牛。。

hdparm-Tt /dev/sda

/dev/sda:
Timing cached reads:   2636 MB in2.00 seconds = 1316.23 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device
Timing buffered disk reads:184 MB in3.00 seconds =61.30 MB/sec
HDIO_DRIVE_CMD(null) (wait for flush complete) failed: Inappropriate ioctl for device

你用的是什么硬盘？

/dev/hda:
Timing cached reads:   2620 MB in2.00 seconds = 1309.92 MB/sec
Timing buffered disk reads:   84 MB in3.06 seconds =27.41 MB/sec

第二个测试很低，笔记本硬盘的瓶颈吧。

# hdparm -Tt /dev/sdb

/dev/sdb:
Timing cached reads:   1612 MB in2.00 seconds = 805.95 MB/sec
Timing buffered disk reads:166 MB in3.01 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

谁说没意义，俺的缓存有16M :mrgreen:
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
