So pending is constantly > 0? What are the clients? Is it batch jobs or something similar where there is a feedback mechanism implicit in that the higher latencies of the cluster are slowing down the clients, thus reaching an equilibrium? Or are you just teetering on the edge, dropping requests constantly? Under typical live-traffic conditions, you never want to be running with read stage pending backing up constantly. If on the other hand these are batch jobs where throughput is the concern, it's not relevant. -- / Peter Schuller (@scode, http://worldmodscode.wordpress.com)
