 Posted: Fri Nov 11, 2005 2:50 pm Post subject: Good hdparm results but slow harddisk |
 |
|
My system feels unresponsive at times because my harddisk feels slow.
I've recently update the harddisk in my laptop from the default 4200RPM 2MB cache disk to a Western Digital 5400RPM 8MB disk.
Hdparm results seem good but the problem is that when a directory is read for the first time it takes a long time (>1 sec.) before the contents show up. After it's cached everything is fine.
The old and new disk both run reiser3.
So what's up? Why does my faster drive feel slower?
| Code: |
root@~/# hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 65535/16/63, sectors = 80026361856, start = 0
root@~/# hdparm -tT /dev/hda
/dev/hda:
Timing cached reads: 1592 MB in 2.00 seconds = 795.95 MB/sec
Timing buffered disk reads: 92 MB in 3.02 seconds = 30.46 MB/sec

| It is mounted as the first device as master on the first IDE cable. Is that what you mean? |

Ok, here it is:
| Code: |
$ mount
/dev/hda5 on / type reiserfs (rw,noatime,notail)
|
And from fstab:
| Code: |
/dev/hda5 / reiserfs noatime,notail,defaults 0 0
