You're disks aren't slow, but my algorithm is.

I make no attempt to optimize the update algorithm for the fact that if
you used fastbuild, your keys are distributed more or less randomly
around the disk.  That means you do a LOT of seeking, and seeking is
slow.

It's something I'd like to fix, but simply haven't had time time for it.
