The article is indeed interesting underlining several cache miss aspects and performance impacts, but sorting 1e8 ints in 7s with standard lib vs 4s (with complex and subtle insights, and maybe sensitive to cpu arch) might not be worth it if you're dealing with a database, or with not that experienced coworkers, or deaking with a more complex computation. So does 2x matter? The article doesn't say, but it is interesting nonetheless.
