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 64Bit and use xfs filesystem
Old one is Ubuntu 7.10 32Bit and ext3 filesystem
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:
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..
