Hi,
since I replaced my Abit KT7 with an Elitegroup K7S5A Pro (SIS735), I've got extremly low disk performance with every tested kernel version (2.4.20, 2.6.0-test6-mm2):
# hdparm -tT /dev/hda /dev/hda: Timing buffer-cache reads: 824 MB in 2.00 seconds = 411.65 MB/sec Timing buffered disk reads: 10 MB in 3.28 seconds = 3.05 MB/sec ^^^^
DMA, 32bit etc. is activated (hdparm -d1 -c3 -u1 /dev/hda):
# hdparm -v -i /dev/hda /dev/hda: multcount = 16 (on) IO_support = 3 (32-bit w/sync) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 65535/16/63, sectors = 117231408, start = 0 Model=ST360021A, FwRev=3.10, SerialNo=3HR0E280 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% } RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=4 BuffType=unknown, BuffSize=2048kB, MaxMultSect=16, MultSect=16 CurCHS=4047/16/255, CurSects=16511760, LBA=yes, LBAsects=117231408 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120} PIO modes: pio0 pio1 pio2 pio3 pio4 DMA modes: mdma0 mdma1 mdma2 UDMA modes: udma0 udma1 udma2 udma3 udma4 *udma5 AdvancedPM=no WriteCache=enabled Drive conforms to: device does not report version:
Any hints how this problem could be solved?
