Bug#270199: kernel-image-2.4.26-1-686: Poor ATA I/O performance
Package: kernel-image-2.4.26-1-686
Version: 2.4.26-2
Severity: important
I've just filed a bug report against 2.6 for this same system; 2.6 does
not work on this system, so I have no workaround.
Here is my fully-tuned disk I/O performance:
ns:~# hdparm -t /dev/hda{,}
/dev/hda:
Timing buffered disk reads: 18 MB in 3.32 seconds = 5.42 MB/sec
/dev/hda:
Timing buffered disk reads: 18 MB in 3.31 seconds = 5.44 MB/sec
ns:~#
Expected performance on this hardware is 25-30 Mbytes/sec.
The drive:
ns:~# hdparm -i /dev/hda
/dev/hda:

Note that DMA is not turned on, and I cannot turn it on.
Tuning:
ns:~# hdparm -d1 -c1 -k1 -K1 /dev/hda
/dev/hda:
setting 32-bit IO_support flag to 1
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
setting keep_settings to 1 (on)
setting drive keep features to 1 (on)
HDIO_DRIVE_CMD(keepsettings) failed: Input/output error
