Working with ny openstreetview data (can be found in mongo-snippets/2dsphere/data) which results in 366440 entries.

When doing a db.ny.find().count(), it returns instantly.

If I do a db.ny.find({geo: {$near: {$geometry: {type: "Point", coordinates [any lng, lat ]}}}}).count()

it hangs for a long time, and eats all of my memory.
