Having a look at hdparm definitely might give your system a boost. Probably
just enabling (U)DMA helps a lot (hdparm -d /dev/hda). (On my system it
increases the speed of disk reads from 4 MB/s to 35 MB/s!) I have noticed that
when using DMA other options don't seem to make a difference (at least not on
newer machines, on an old 486 setting block mode and 32 bit mode might be a
better idea than using DMA), so setting 32 bit mode (-c 1 or -c 3) or block
mode (-m x) is not necessary in this case.
Adjusting filesystem buffers (-f x) seems not to make a difference when
running hdparm -t, but in real life situations, for example on large dd's
setting this to a high value increases throughput significantly.
Hope this helps,
Leonard.
