Workload analysis

Edit online

This topic presents the workload specific results of the study. Results from each individual workload from the combined workload set is presented in a separate subtopic. Because of the amount of data, detailed results are exposed only for the z/VM 6.3 environment with EDEV-SCSI paging. This environment is well suited to uncover the basic interrelations.

Reference result describes the reference workload result, which sets the base against which all other measurements are compared.

In Scaling memory and number of processors, the overall z/VM CPU load behavior is inspected when running the combined workload set in selected resource constrained z/VM configurations.

Finally, the test results are described that resulted from executing each individual workload from the combined workload set in z/VM configurations, where the amount of real memory or the number of real CPUs, or both, were reduced. For details, see Test configurations and Test procedure.

Each workload is described in a separate topic. The focus in these topics is on analyzing the individual workloads with respect to their throughput, generated CPU load, memory usage and generated paging workload.
