Yes, this kind of latency definitely says "indexed". When I wrote this, I'd read a rethinkDB employee say "it's not using the index on rethinkdb", and performance was similar (3x) between the two. I trusted the "no index" path, and couldn't find an ensureIndex command... So I assumed there was no index on mongodb. Truth is, this kind of performance can only come with indexes, on RethinkDB and mongodb.
