Recently I built a new box with i7 cpu 6Gb of ram and SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5"

The new box is running Ubuntu 10.04

I noticed that this powerful machine I built runs slower than my 3yrs old box when it comes to IO intensive tasks. For example when I run simpletest (testing framework) on my codebase it takes 3-5 more time on the new box..

Is there a way I can try to pin point this problem and make sure that hardive is a problem (or not).

I did run bonnie++ test on both boxes:

Old - New box -

When I was comparing 2 reports I spotted big difference in Sequential IO Per Chr section.

What can cause such a difference and is it the indicator of the potential problem?

I hope to hear some suggestion and recommendations for further debugging..

This question came from our site for system and network administrators.

If this is a workstation this should be moved to superuser. If this is a server, what is the architecture of the old box? Are you using the same filesystems on both? – Mike Mar 23 '11 at 21:45
Hi. Yes, it's a workstation. Should I just copy paste the question to poveruser, or there is a way to move it. Old box is on ext3 (Ubuntu 7.10 32bit) and new one is xfs (Ubuntu 10.04 64bit). – gansbrest Mar 24 '11 at 14:58
What kernel-version do you have? (run uname -r)? Have you updated/upgraded it all? – Bart De Vos Apr 15 '11 at 13:36

check S.M.A.R.T. data- run Hard Drive Utility:


this is form “gnome-disk-utility” package, it is a GUI and see under SMART info

Also check in BIOS if this SATA port is part of some RAID configuration and disable it

can move the disk to different SATA channel with different cable even on different motherboard
