If needed, you should simulate a load that represents the load condition that you are expecting on Cassandra. This will give you a baseline for what to tune. It will be helpful to keep some profiling running at the OS level to gauge what resource is getting depleted—things such as JConsole, nodetool cfstats, and tpstats.
