https://bugzilla.novell.com/show_bug.cgi?id=267444 Summary: Thinkpad Z61p S-ATA disk very slow with openSuSE-10.2- 64bit Product: openSUSE 10.2 Version: Final Platform: x86-64 OS/Version: openSUSE 10.2 Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: teheo@novell.com ReportedBy: ffiene@veka.com QAContact: qa@suse.de My brand new Thinkpad Z61p is slower than my "old" T42p. Z61p: T7200 Dual2 Core 2GHz, 4GB RAM, 100GB S-ATA T42p: Centrino (Dothan?) 2GHz, 2GB RAM, 100GB IDE I found a possible issue: accessing S-ATA HD slows down the system. If i try "find / -name <bla>" the system is turned into a brick until find has been completed. "top" shows jumping 100% WA (wait IO?) from one CPU to the other. First i tried to find out if XFS or 64bit is the problem. 1.) XFS is not the problem, doing the same find on a LUKS-encrypted, XFS formatted USB HD is much more faster and "top" shows no WA. 2.) 64bit seems also not the problem, starting Ubuntu-7.04-64bit from CD, mounting HD with same mount options (noatime, nobarrier) shows a great performance! 3.) I've tried the kernel of the day, it was 2.6.21-rc7-git5 but no success, it has the same issue! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
