Workload scaling
One exemplary ECM workload scaling measurement series is discussed here.
The ECM workload was increased until all available CPUs on the CE/PE guest were fully utilized. The number of CPUs on the CE/PE guest is considered as the limiting factor for the SUT at the highest possible throughput rate for a scenario.
The measurement series for the other CE/PE guest CPU configurations behave similarly at lower (for 1 CPU) or accordingly higher (for 4 and 8 CPUs) throughput rates. The 2 CPU scenario is discussed in the following section. The other measurements series will be described in the vertical CPU scalability discussion later on.
