Disk operations freeze Debian
- by Grzenio
Hi,
I have just installed Debian testing on my new desktop and I am not very happy with performance - when I perform a disk intensive operation, e.g. upgrade packages in the system, everything seems to freeze, e.g. changing tabs in Iceweasel takes 3 seconds. I run the Debian on my 3 year old Thinkpad X60 ultra-portable, and I don't have these issues. (every single parameter of the laptop is much worse than the desktop).
I am using the default packaged kernel and scripts.
I run
hdparm -t /dev/sda1
And I got around 96GB/s, which is expected. What else can I try to make it work better?
EDIT:
grzes:/home/ga# hdparm -i /dev/sda
/dev/sda:

EDIT2: Even my wife said "on this new computer I can't do anything when I copy the photos from the camera and its much worse than on the old one". So it must be serious.
EDIT3: Updated to 2.6.32, but still no improvement
EDIT4: I forgot to mention that the new disk is ext4, the old was ext3.
EDIT5: Still not solved. I have a P43 ASUS P5QL-E board. Lines from dmesg that seem relevant:
