Sorry for being late in the conversation, I was away from the tubes for some time...
So currently the batching is done by region, not region server. When I implemented the write buffer, I saw that we can save a lot in the first few RPCs we cut but then it stays pretty much stable (see the graph in the jira about that). So grouping by region server would be a bit more complicated IMO and it wouldn't save much... if not nothing at all.
