what's the goal? the absolute smallest repository
or access speed? sharing means seeks. seeks are
deathly slow if you're using disks.
there was a time when there was a compelling
argument for reducing the number of i/o operations
for performance by increasing the block size.
i'm not sure that argument is as strong as it once
was.
