They are driven by two completely separate driver stacks, so you need to isolate them. * In the info you posted in the previous comment, suse 10.2 shows normal performance of 61.68MB/s buffered disk reads. In the first report, the problematic device is /dev/hdb but it isn't present on boot messages of both 10.1 and 10.2. If you're talking about performance difference in 'Timing cached reads', that's not a driver problem. It's determined by VM. ISTR related discussion on LKML but cannot find it at the moment, but I would be surprised if that has any bearing on real world performance. Keep in mind that hdparm's cached read test is as synthetic as a benchmark can get. -- 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.
