I have done an installation of a new openSUSE 12.3 system. Amongst the odd problems I am having is slow file copying. It makes no difference what physical drives are involved. Copying an 80 MB takes 15-20 seconds. Bigger files taks correspondingly longer. It makes no difference if the copy is to the same directory or to a different partition or even a different disk. On a different 12.3 install with similar (not the same) hardware, the copy takes less than one second. Copying over the network to a computer in another city is faster... Copying to /dev/null is fast as expected. So it seems that it is the writing to a disk part that is the issue. The file systems are ext4 with the default settings used from installation. The system has these disks: [0:0:0:0] disk ATA WDC WD1000DHTZ-0 04.0 /dev/sda [1:0:0:0] disk ATA WDC WD2000FYYZ-0 01.0 /dev/sdb I see this in /var/log/messages, scsi 0:0:0:0: Direct-Access ATA WDC WD1000DHTZ-0 04.0 PQ: 0 ANSI: 5 sd 0:0:0:0: [sda] 1953525168 512-byte logical blocks: (1.00 TB/931 GiB) sd 0:0:0:0: [sda] 4096-byte physical blocks sd 0:0:0:0: [sda] Write Protect is off sd 0:0:0:0: [sda] Mode Sense: 00 3a 00 00 sd 0:0:0:0: [sda] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA scsi 1:0:0:0: Direct-Access ATA WDC WD2000FYYZ-0 01.0 PQ: 0 ANSI: 5 ACPI: Invalid Power Resource to register! sd 1:0:0:0: [sdb] 3907029168 512-byte logical blocks: (2.00 TB/1.81 TiB) sd 1:0:0:0: [sdb] Write Protect is off sd 1:0:0:0: [sdb] Mode Sense: 00 3a 00 00 sd 1:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA sdb: sdb1 sd 1:0:0:0: [sdb] Attached SCSI disk sda: sda1 sda2 sda3 sd 0:0:0:0: [sda] Attached SCSI disk I do not see any complaints about the disks in the log file. To my eyes all looks as expected. Except for the slow speed. I am not sure what else to look at at this time. Anyone have any pointers? -- Yours sincerely, Roger Oberholtzer Ramböll RST / Systems Office: Int +46 10-615 60 20 Mobile: Int +46 70-815 1696 roger.oberholtzer@ramboll.se ________________________________________ Ramböll Sverige AB Krukmakargatan 21 P.O.
