I tried this too, it takes ~2s on my homedir. I put the extra .9s down
to the IO time for extra info that -ls adds and sort having to move it
around. Also the output of find -ls can be a bit cryptic due to the
inode number and kilobyte count, so I rejected that in favour of
something that outputed only the size and path. The -printf can be
tweaked to add more info if its needed.
