100x faster: Don't sort.

  Fair :) Sorting is useful in DB joins/group-by, though. (Author here, happy to discuss.)

  At first glance seems like a snarky dismissal, but this is actually valid, actionable advice. If you can arrange your data flow in such a way that sorting is unnecessary, you've avoided an expensive optimization problem altogether.

  No sorting is faster than no sorting.
