SubjectRE: IDE0 /dev/hda performance hit in 2217 on my HW
Date
According to hdparm, dma was already on.  It was also suggested I try
setting
32-bit mode and multcount (which I had tried before and not noticed much
difference).
Here's the current settings and results. Note that the timings still don't
make
alot of sense when comparing them to the vmstat numbers. All transfers were
256M (bs=256k, count=1k).

/dev/hda:
multcount = 16 (on)
I/O support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 3278/240/63, sectors = 49577472, start = 0
