Yes, I was referring to memory space, and when that hits swap, taking more
space usually means more time.  And of course, if one runs out of memory,
then it's even worse.  I wouldn't bother storing the hunk sizes on disk,
since that would change the patch format (bad), and wouldn't really gain in
performance unless you also stored the number of characters--by size I mean
number of lines, which is what's relevant when doing commutations.
