@dbtsai I see, it would be great, though, to check which is this threshold.
My understanding is that the current solution has better performance even for
several hundreds of items. If this number is some thousands and since this
depends on the datatype (so it is hard to control by the users with a single
config), it is arguable which is the best solution: I don't think it is very
common to have thousands of elements, while for lower numbers (more common) we
would use the less efficient solution.
