Steps To Reproduce:
Hide

Import the attached database and run the query:

db.PolygonDescription.find({ $query: { geo: { $geoIntersects: { $geometry: { type: "Point", coordinates: [ 10.5891, 49.77997 ] } } } }, $explain: true }, { _id: 1 })

Delete the last document (id=56179fa25495b1184924b03e) and rerun the query. You'll see a marginal speedup, by just removing this one document.

Test Environment: Windows 10 x64, MongoDB 3.0.6

I have a very small database with 9999 Polygons (their coordinate consists of just 5 Points).

Querying the set with geointersects (using a geosphere index) is fast, until I add one more polygon (which covers all others and has a large coordinate set > 130000 points).

I'll add the mongoexport of my database.

Explain without the last "huge" polygon:
