Do you think we are psychics who can guess at your problem when you've
shown us none of the table definitions, none of the query, and only a
small part of the EXPLAIN output?

Donning my Karnak headgear, I will guess that this is actually not a
SELECT query but some kind of update operation, and that the time
sink is in the updating part and not in the data extraction part.
(Inefficient foreign-key operations would be a likely cause, as would
poorly written user-defined triggers.)  But that's strictly a guess.
