You need to consider the correlation between the cpu speed, the disk
speed and the controller type.  If the disk controller on the sparc is
a really slow SCSI card, then the kernel will have offloaded some cpu
operations at the cost of waiting longer for the operation to
complete.  Compare this to a newer system that uses the more cpu
intensive IDE controller which, once set in motion, writes much

You are really comparing apples and avocados.
