I did a quick rethinkdb vs mongodb test. I made two meteor apps, one with meteor-rethinkdb https://github.com/Slava/meteor-rethinkdb and the other mongodb with oplog and put them on Galaxy. Inside a setInterval I inserted, updated then removed from the db over and over.
1 container with one client connected
Mongodb - Each loop took about 2200ms. Cpu at 0.35
Rethink - Each loop took about 900ms. Cpu at 0.15
Rethink wins!
scaled to 6 containers
Container that had two clients connected to it.
Mongodb - Cpu at 0.5
Rethink - Cpu at 0.4
Container that had one client it.
Mongodb - Cpu at 0.5
Rethink - Cput at 0.2
Containers that had no clients connected.
Mongodb - Cpu between 0.23 and 0.34
Rethink - Cpu between 0.01 and 0.06
Rethinkdb crushes Mongodb!!!
I’m having issues with cpu I think because of oplog and livequery and I’m thinking about trying to use meteor-rethinkdb. I have no idea about the state of it though. Is anyone using it with success?
