   Closing this ticket as I believe it is not tracking anything anymore.
   
   SortPreservingMerge is now implemented as an n-way tournament tree making use of an order-preserving row encoding for multi-column sorts, and specialized cursors for single column sorts. I'm not aware of any major low-hanging fruit to make it run faster
