No, 8/minute 32/minute are not high rates. This is really strange. Can you tell me anything about the entities? Are they large? Could they have exploding indexes? We need to get to the bottom of why these ops are timing out. Are these timeouts correlated with the latency spikes in master/slave datastore?
