> Currently, many critical thread pools are sized according to the number of available processors i.e. Runtime.getRuntime.availableProcessors() (See StageManager.java)
> In a multi-instance deployment, multiple Cassandra instances will independently assume that all processors are available to it; there should be a mechanism to specify a smaller set of processors (and perhaps have affinity).
