That's what i was thinking, but 30MB/s seems to be quite an exaggeration.
On my
Intel Corporation 82371AB PIIX4 IDE (rev 01), ide chipset my master (10.2GB
maxtor 7200rpm UDMA66) drive i get ~15-16MB/s and on my slave (same
interface, 20.1GB maxtor 7200rpm UDMA66), i get ~13MB/s. This goes against
logic as the bigger the drive the faster the transferrate should be, and
it's about half of your estimate of Michael's 40GB. Is this due to the
slow disk access of 2.4.0-test10-preX ? Or am i experiencing a bug here?
Both drives are operating at UDMA33 mode (according to hdparm) and both
drives are set to using 32bit, dma, 16 sector read ahead and 16 sector
multi-access mode. I've posted results i've gotten from bonnie and
bonnie++ before, in all cases, the performance seems to be lacking for the
kind of hardware i have.
