Chapter 4. Workload Identification and Characterization
We describe the need to specify the functionalities of a system and to identify the nature of the performance characteristics each functionality must have to be effective. The notion of a reference workload will be introduced as a vehicle for specifying a straw workload for the purposes of when several workloads are possible. We shall discuss the impact of time-varying behavior on system performance—for example, whether the load offered to it is rhythmic and regular, whether it varies seasonally or by time of day, whether it is growing over time, and whether it is inherently subject to potentially disruptive bursts of activity. These workload characteristics must be understood for performance ...
