Could it be that your disk(s) aren't running in DMA mode?

how does DMA help? should this be on for all machines (eg mine!)?

DMA stands for direct memory access.  It allows capable drives and
controllers to access memory while bypassing the CPU.  This means that
since the CPU is not required to arbitrate every transfer to and from
memory: a) they complete much faster, and b) your overall CPU load is
significantly less.
