I just installed OpenSuse 10.2 and found my HDD working really slow. HDDcontoller hp dc5100MT 00:1f.2 IDE interface: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Controller (rev 03) (prog-if 8f [Master SecP SecO PriP PriO]) Subsystem: Hewlett-Packard Company Unknown device 300c Flags: bus master, 66MHz, medium devsel, latency 0, IRQ 201 I/O ports at 1818 [size=8] I/O ports at 1830 [size=4] I/O ports at 1820 [size=8] I/O ports at 1834 [size=4] I/O ports at 14f0 [size=16] Capabilities: [70] Power Management version 2 When installing my PC I found the HDD working really slow so I tested it with hdparm -Tt /dev/sda (S-ATA) # hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 1440 MB in 2.00 seconds = 719.95 MB/sec Timing buffered disk reads: 186 MB in 3.03 seconds = 61.47 MB/sec HDD: /dev/sda: ATA SAMSUNG HD080HJ/ ZH10 So I tought it would be the HDD working really slow so I installed a different HDD (ide) # hdparm -Tt /dev/hda /dev/hda: Timing cached reads: 1446 MB in 2.00 seconds = 722.77 MB/sec Timing buffered disk reads: 174 MB in 3.03 seconds = 57.37 MB/sec Das ist mir alles zu langsam. # hdparm /dev/hda /dev/hda: multcount = 16 (on) IO_support = 1 (32-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 65535/16/63, sectors = 78165360, start = 0 At my second PC HP DX6100 SUSE 9.3 there is no problem: HDDcontroller hp DX6100: 0000:00:1f.2 IDE interface: Intel Corporation 82801FB/FW (ICH6/ICH6W) SATA Controller (rev 03) (prog-if 8f [Master SecP SecO PriP PriO]) Subsystem: Hewlett-Packard Company: Unknown device 3005 Flags: bus master, 66Mhz, medium devsel, latency 0, IRQ 201 I/O ports at 3818 [size=8] I/O ports at 3830 [size=4] I/O ports at 3820 [size=8] I/O ports at 3834 [size=4] I/O ports at 34f0 [size=16] Capabilities: [70] Power Management version 2 # hdparm /dev/hdb /dev/hdb: multcount = 16 (on) IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 19457/255/63, sectors = 160041885696, start = 0 # hdparm -Tt /dev/hdb /dev/hdb: Timing cached reads: 3188 MB in 2.00 seconds = 1591.85 MB/sec Timing buffered disk reads: 48 MB in 3.02 seconds = 15.88 MB/sec Thats really slow (especially at the cached reads) alt = 1591.85 MB/sec neu = 722.77 MB/sec 2neu= 719.95 MB/sec As I could not believe that this is a software bug, I installed OpenSuse 10.1 And it really is faster: # hdparm -Tt /dev/sda /dev/sda: Timing cached reads: 2964 MB in 2.00 seconds = 1483.99 MB/sec Timing buffered disk reads: 180 MB in 3.00 seconds = 59.97 MB/sec # hdparm /dev/sda /dev/sda: IO_support = 0 (default 16-bit) HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device HDIO_GET_DMA failed: Inappropriate ioctl for device HDIO_GET_KEEPSETTINGS failed: Inappropriate ioctl for device readonly = 0 (off) readahead = 1024 (on) geometry = 9729/255/63, sectors = 156301488, start = 0 So it seems to me that this is a bug, isn`t it ? -- 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.
