The image embedded in the Gist says 10Gb network.

Hi, I'm the original author. I think that GCE instance has 2Gb per core but I'd need to check. It wasn't bottlenecked on network bandwidth though.

The other benchmarks are linked in the spreadsheet to their respective details. It's not an absolute, direct, fair comparison. However, we wanted to start somewhere with information available right now and try to collect better results over time as the respective interested parties benchmarked and blogged about their databases.

I'd like to spend more time benchmarking every database in the spreadsheet but it feels like something the project owners should do themselves. I'd probably only get the setup wrong.
