my system is running very slow, took over 3 minutes to load xfce and i've got a 3.0ghz 512megs of ram machine. Anyway i ran hdparm and these are the results,
debian:/home/sofa# hdparm -Tt /dev/hda
/dev/hda:
Timing cached reads: 2456 MB in 2.00 seconds = 1227.57 MB/sec
Timing buffered disk reads: 2 MB in 8.26 seconds = 247.95 kB/sec
that can't be right but i've done the test 3 times. The harddrive isn't clicking or anything but could this be the reason everything is running so slow?
The value from the "Timing buffer-cache reads" looks pretty good. The value from the "Timing buffered disk reads" (i.e. STR) does not. What kind of hard drive is it (i.e. manufacturer, size, type of interface, etc)? How long have you had it?
May want to try this command and see what info it tells you about the settings for the drive.

Compare yours to mine and see what yours is set up as. It could be that there is a IDE chipset problem and it is not using nothing but the generic drivers. They are very slow. The part with "capabilities" is the important part, usually anyway.

The drive is a western digital 120gig (WD1200JB) 8 meg cache. I've had it less than a year. Here is my hdparm -I /dev/hda printout

Looks like it is using udma2 instead of the newer udma5 or udma6 modes. I'm not familiar with Debian but you may want to find out about that chipset driver. It is usually in the kernel or in as a module. I'm not sure about how Debian is set up. Sorry.
