Additionally, appending  for lines gives a significant gain over using -n, so that needs works as well.

EDIT: I agree that '-n' should be what is used here, I was moreso posting in the interest of figuring out why that's so slow. I just made a PR which seems to bring the time for '-n' to be more like that of 'for lines'
