Mónica - that is a surprising difference. Could you add &debug=true and share
the parsed queries you're getting in both cases?
What is the layout of your collection? multi-sharded? how many shards? Is
the index in flux (things being added or deleted) between those queries? Any
other architecturally relevant factors involved?
Best,
Erik
