Anybody using a replicated setup, with say at least 5-10 nodes or so? If so can you state an average load in terms of ops/sec and cpu?

He said Mongo was durable and unless I am missing something, Mongo openly admits that they trade durability for speed. CouchDB is probably the most durable solution out there I think (I regularly just kill an amazon ec2 instance in the middle of something and never had a problem...), which is something he says he values when he recommends Tokyo, Mongo and Redis. I am really curious why he says he wouldn't even consider using CouchDB. I am using CouchDB with a rails 3 app right now and I have not noticed any problems. I would love to hear what everyone else thinks. Is there some big problem hanging out there that I don't know about?
