In that thread I pointed out that bulk testing btree *lookup*
performance is best done with lookup keys in *random* order, since
btree will perform artificially well when the *lookup* keys are
sorted.
There is no claim that btree *insert* performance is faster with
sorted data, it may well be much slower.
