System slow?

Hi,

I feel that my system (Debian squeeze) is a bit slow.. I suspect it could be a hard disk issue..
Which is the "normal" value for hdparm, in case of IDE hard disk?
Here is my output:

# hdparm -i /dev/hda

/dev/hda:

/dev/hda:

From memory, I would expect to see 35 to 40 MB/s. Maybe up as much as 50MB/s from the front of a newer IDE drive with a tail wind!
