Out of curiosity, did you have an index on the ts field that you are matching with?

By the way, if you (or anyone else for that matter) come up with useful benchmarks I'd love to get a copy of them at [e-mail]. I have a few of my own, but I'd like to get some real-world workloads from the community to test potential optimizations against.

Yes, I had a single index:

  db.events.ensureIndex({ ts: 1 });

I'll try to clean up my benchmark code a little, throw it in a gist, and then I'll send it your way.

Update: already forwarded this to Mathias, but posting here in case anyone else wanted to see the full benchmark test: https://gist.github.com/3518344
