In my experience five 100-line diffs get reviewed much faster than one 500-line diff. Especially when you follow best practices like splitting refactors from functional work; the canonical stacked diff for me is “refactor to make the upcoming change easy; add some tests for the existing functionality I want to protect; small diff to actually make the change”. 1 & 2 don’t generally require caffeine to review. 3 probably requires engaging the brain. If you put everything together you need to be on high alert for the whole review.
