I was wondering the exact same thing -- how can CPU-parallelism improve on a task which (to me at least) seems to be disk-IO bound? I'm guessing that my assumption of the task being disk-IO bound is incorrect!

It's only disk IO bound if you're accessing the disk. With modern servers packing multiple TB of memory, it is likely you won't be accessing the disk at all.
