That is probably due to getting rid of the pci bus. Here's a hardware raid (3ware 9650SE, 5 x 750 GB Seagate SATA2):
mordor:~ # hdparm -tT /dev/mapper/system-var
/dev/mapper/system-var: Timing cached reads: 13236 MB in 2.00 seconds = 6626.75 MB/sec Timing buffered disk reads: 1130 MB in 3.00 seconds = 376.05 MB/sec
Here's the data of my old server (old pci hardware raid, 3 x 18 GB SCSI):
/dev/rd/c0d0p3: Timing cached reads: 298 MB in 2.00 seconds = 148.70 MB/sec Timing buffered disk reads: 62 MB in 3.02 seconds = 20.56 MB/sec
Quite a difference. (^-^)
The SCSI transfer speed also matters a lot - those 18Gb drives were pretty slow when compared to todays U320 drives. /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
