Setting the number of write nodes and read nodes to match your workload. I was scaling up a system and as more things came online, the traffic became more bursty we were constantly bumping them up and wondering if we were allocating too much (probably useless fretting regardless). Ultimately, we moved to an S3 only solution since we have such a low throughput environment and the simplicity is addictive.
