I noticed `Model.count` was slow, after looking into the logs I noticed its doing `db.model.aggregate([{'$match': {} }, { '$group': { _id: 1, count:

} }])`. This seems very very odd and explains why this is slow. I would expect it to use `db.model.find({}).count()` (if i do `Model.collection.count` it is fast, as i would expect cause its using the db.model.find({}).count()`)
