of course the time is related to the type data you are fetching by one query.
if the type of data is larger than 10000 items, you need reindexing for this result. and recount each time for getting the proper item. it seems you have not encountered such a problem. on this situation, the indexes on the fields helps nothing for the bulk of data you have to be sorted is really big.
