In a kernel that has both IDE and nfhd support, once everything is in the

So nfhd is slower than emulated IDE?
That seems odd indeed ... is the disk attached as IDE or via USB adapter?
(Checking to see whether I should get similar results)
It's not a physical disk:
[IDE0]
Present = Yes
IsCDROM = No
ByteSwap = No
ReadOnly = No
Path = /scratch/geert/aranym/etch-m68k.img
Cylinders = 2102
Heads = 16
SectorsPerTrack = 63
ModelName = Sarge m68k
